APRIL'S  SHOWERS  '94 


Don't  shoot  the  editor!  It's  ty  fault  that  this  issue  is 
late.  I've  been  working  on  a  fey  things  and  let  too  much 
stuff  slip  by. 

Host  of  the  information  for  this  issue  has  been  written  or 
provided  by  Hugh  Howie,  our  QL  Librarian  and  QL  Liaison. 

Where  have  all  the  users  gone? 

In  the  last  year  we  have  seen  a  draiatic  drop  in  the  ZX81 
and  2068  club  participation.  Our  book  libraries  have  not 
been  active  for  several  years,  and  the  tape  and  disk 
libraries,  with  the  exception  of  the  QL  libraries  run  by 
Hugh  Howie,  have  also  become  inactive. 

I  think  that,  in  lost  cases,  users  of  the  ZX81  and  2068, 
have  lade  the  juip  to  other  systeis  with  their  increased 
■eiory,  video  and  availability  of  hardware  and  software  at 
reasonable  prices.  Indeed,  you  can  now  find  complete 
systeis,  although  used,  at  prices  that  first  attracted  us  to 
the  Sinclair  computers.  Hany  users  have  simply  packed  up 
their  old  systems  and  stored  or  given  them  away.  Our  loss 
but  understandable,  considering  that  both  the  ZX81  and  2068 
have  been  out  of  production  for  about  10  years. 

This  scenario  does  not  apply  as  such  to  the  QL  earket.  There 
is  still  considerable  activity  both  in  Europe  and  in  North 
America  for  the  QL.  Witness  the  development  of  a  new  Sold 
Card  and  the  occasion  of  another  QL  computer fest  in  Newport 
as  reported  in  this  issue. 

Where  do  ve  go  from  h*re? 

The  strength  and  vitality  of  a  club  can  be  judged  by  the 
active  participation  of  members  in  the  club  and  this  can  be 
reflected  in  the  newsletter.  That  being  the  case,  we  as  a 
club  need  a  booster  shot.  Summer  is  just  around  the  corner 
and  is  traditionally  the  hardest  time  to  get  material  for 
the  newsletter.  As  can  be  seen,  there  is  lots  of  QL  material 
and  Hugh  has  indicated  that  he  has  barely  scraped  the 
barrel.  Maybe  we  should  change  the  name  from  SINC-LINK  to 
SINfl-UNK.  Think  about  it.

O      L      I      P  S. 


by  Ingh  Bowie 


I  like  to  think  I  am  no  different  from  most  other  QL  users,  or  at  least, 
not  too  different,  and  that  therefore  I  have  problems  similar  to  others. 
Anyway,  here  is  ray  solution  to  one  of  my  problems. 

How  I  have  often  wished  I  could  get  hard  copy  of  something  on  screen,  a 
Screen  Dump,  and  was  unable  to  do  so,  yet  there  is  a  little  known  procedure 
in  the  Trump  Card  and  Gold  Card  manual  to  do  just  that,  and  on  this  page 
you  see  an  example.     OK  OK  so  I  had  to  do  a  double  pass  of  the  paper  in  the 
printer,  but  at  least  you  can  see  what  I  dooed. 

The  procedure  is  towards  the  end  of  the  Trump  or  Gold  Card  manual,  and  just 
before  the  TK2  section  gets  going.     It  is  available  even  before  the  TK2  is 
activated.     There  is  also  a  section  giving  you  "screen  dump  formats"  for  a 
number  of  different  printers. 

Oh  dear,  I  almost  forgot  to  tell  you  what  the  darned  thing  is  it  is  so  easy 
to  use.     Just  type        4>dp_jL<Ly  q       and  from  then  on,  whenever  you  press 
the  "ALT  &  q"  you  will  send  a  screen  display  to  the  printer.     (Put  it  in 
all  your  BOOT  files,   just  after  TK2_EXT,  then  it's  always  ready  for  use) 
There  are  some  occasions  when  such  is  not  the  case  such  as  when  the  QL  is 
expecting  input  from  another  source  etc.     Let's  try  it  -  Type  in:~ 
AdpJ*,Q*y         then  press  ALT  S  q, .

Now  that  was easy  was  it  not?  Why  not  look  it  up  and  try  it  out?  You  will 
find  many  uses  for  it,  just  as  I  did  here  in  this  little  bit  of  natter. 

As  I  said  some  time  ago,  most  of  us  don't  know  what  there  is  lying  around 
inside  this  little  black  beast,  and  it  only  takes  a  few  moments  to  look  at 
the  manual  to  find  out.     Sorry,  I  forgot  that  most  of  us  don't  read  the 
manuals  -  we  are  far  too  smart  to  need  them.

The  heading  may  make  you  think  you  are 
listening  to  a  flock  of  ducks  on  the 
local  millpond.  or  a  skein  of  geese  on 
their  annual  migratory  pilgrimage  flying 
high  overhead.  But  really  "QLerk"  is  the 
name  of  a  program  by  the  renowned  New 
Hampshire  programmer,  Bill  Gable. 

Bill  has  spent  a  lot  of  time,  a  lot  of 
work,  on  this  program,  and  he  has  tested 
it  in  various  businesses  in  his  area. 
The  result  is  a  program  that  will  keep 
your  business  records  in  order,  or  even 
just  your  household  finances  in  order. 
The  only  limitation  on  the  uses  of  this 
program  are  what  the  user  places  on  it 
himself. 

I  was  lucky  in  being  able  to  look  at 
version  2.1,  but  now  I  have  version  3.0, 
and  the  improvement  is  significant.  I 
will  not  mention  the  previous  version 
again,  as  that  would  serve  no  useful 
purpose,  and  I  only  mention  2.1  to  show 
that  Bill  is  in  a  constant  phase  of 
updating  and  improving  the  system,  and 
that  is  what  it  is  -  it  is  a  system  to 
keep  your  records  up  to  date. 

This  would  be  a  good  time  to  mention  that 
the  program  is  vast.  It  is  very  complex, 
very  comprehensive.  It  is  going  to  take 
the  user  some  time  to  get  to  know  the  ins 
and  outs  of  it.  It  is  not  for  the  faint 
hearted,  but  once  you  have  seen  what  it 
can  do  -  you  will  be  impressed. 

This  is  an  Archive  program,  Archive  being 
provided  on  the  program  disk,  but  can 
also  be  run  using  your  own  Archive.  It 
requires  that  you  have  extra  memory,  a 
minimum  of  512K  extra  memory  would  be 
required.  QLerk  will  run  on  a  7.5MHz  QL, 
but  slowly.  The  Trump  Card  much  better, 
the  Gold  Card  being  best  of  all  because 
of  its  extra  speed  of  operation. 

Disk  drives  are  essential ,  MDV  could  not 
possibly  hold  everything.  QLerk  will  run 
from  two  720  disks.  Or,  if  you  have  HD 
or  ED  drives  or  a  hard  drive,  it  could 
all  be  run  from  the  one  disk.  The 
options  are  there  for  your  own 
configuration. 

To  start  with,  there  is  an  excellent 
manual   which   contains   a   wonderful  demo 


taking  you  through  the  example  setup  on 
the  disk,  one  keypress  at  a  time. 

The  demo  starts  off  by  telling  you  how  to 
make  your  first  backup  of  the  program 
disk,  and  takes  you  through  each  and 
every  step  to  get  the  demo  up  and 
running.  You  are  shown  how  to  use  the 
Menus.  How  to  check  what  payables  are  in 
the  system,  and  how  to  make  payments. 
How  to  handle  receivables,  how  to  write  a 
cheque,  make  purchase  orders,  invoices, 
get  various  reports  from  the  system. 

Once  you  have  run  the  demo  a  couple  of 
times,  you  will  have  an  excellent  idea  of 
how  the  whole  system  operates. 

The  Manual  is  easy  to  read  and  follow. 
It  describes  the  various  Program  Modules 
and  what  each  contains  and  does. 

The  whole  is  menu  driven  and  there  are 
about  a  dozen  and  a  half  of  them.  Each 
menu  contains  about  10  -  12  options,  it 
varies,  and  each  option  has  its  own  set 
of  options. 

Here  is  what  the  Main  Menu  looks  like:- 


lie  to*  uork  on  rare*  (payables jpurchew  ordsri^apnts) 

Receivable  wee.,  uork  on  revenues  (peaiv*lfs,iflwia5,inajie)  I  bank/t

Now  to  keep  track  of  all  those  Menus, 
could  be  a  formidable  task,  but  there  is 
a  complete  page  allocated  to  each  menu. 
That  page  starts  off  with  a  screen  dump 
of  what  the  menu  looks  like,  just  as  I 
did  above,  and  there  is  an  explanation 
under  the  dump,  telling  you  what  occurs 
there.  This  Screen  dump  method  of 
displaying  the  menus,  means  that  vou  can 
refer  to  the  manual  for  a  particular 
menu,  and  see  what  it  does  for  you.  Thus 
helping  you  decide  whether  to  go  back  or 
forward  to  complete  a  task. 

The  facility  on  each  menu  can  be  selected 
in  a  number  of  ways .  You  could  use  the 
up/down  arrow  and  ENTER,  or  you  could 
select  by  the  key  letter  of  the  facility, 
or,  if  you  can  remember  the  number  of  the 
facility  required,  you  can  make  the 
selection  bv  number! 

Should  you  at  any  time  get  out  of  QLerk 
by  pressing  ESC  by  mistake,  just  type  'm' 
and  you  will  be  back  into  the  Main  Menu, 
bo  all  is  not  lost. 

The  system  is  completely  inter-active,  in 
that  an  entry  made  in  one  mode,  is 
transferred  to  all  other  modes  where  it 
is  required,  so  that  if  a  payment  is  made 
by  cheque,  the  money  is  removed  from  the 
bank  account,  the  account  is  reduced 
accordingly.  Where  the  money  went  and 
where  it  came  from,  is  all  recorded 
automatically.  One  aspect  that  Bill 
mentions  in  his  manual,  will  show  just 
how  interactive  the  system  is.  If  you 
were  to  pay  an  account  by  VISA,  the 
account  would  be  paid,  and  the  system 
would  make  out  a  new  account  showing  that 
you  owed  VISA  that  amount* 

The  system  can  handle  up  to  five  cheque 
writing  accounts  at  the  same  time.  Plus 
two  or  three  cash  registers* 

The  cheque  is  filled  out  by  the  printer, 
and  an  address  label  printed  ready  to  be 
pasted  to  the  envelope.  Everything  is 
optional  to  your  own  requirements. 

Payables,  Receivables,  Purchase  orders. 
Cheques,  Invoices,  are  all  available. 
Inventory  control,  Bank  Accounts,  Cash 
Registers,  Taxes,  Duties,  Deductions, 
Cyclical   payments   /   receivables  are  all 


taken  care  of. 

You  want  a  hard  copy  of  some  aspect  of 
the  business?  By  date?  By  occurrence? 
Frequency?  How  often  has  someone  done 
business  with  you  this  last  few  weeks? 
months?  You  name  it,  and  you  will 
probably  find  the  information  is  in  there 
somewhere,  all  you  have  to  do  is  dig  it 
out,  and  with  those  easy-to-use  menus,  it 
is  not  so  difficult. 

There  is  a  complete  Inventory  system  so 
that  you  keep  track  of  everything  in 
stock.  Does  its  own  value  evaluation  for 
you.  Enter  Item,  Price,  and  Number,  and 
everything  is  taken  care  of. 

No  matter  what  you  do,  it  is  almost 
impossible  to  make  an  error.  For 
example,  when  you  make  some  entries,  you 
are  asked  if  you  wish  the  entries  to  be 
merged,  and  you  must  answer  with  Y  or  N, 
thus  you  always  have  the  opportunity  to 
make  corrections  BEFORE  the  documents  are 
altered  or  changed. 

If  you  have  any  questions  to  ask  about 
this  program,  why  not  write  to  Bill, 
after  all  he  can  answer  much  better  than 
I  can,  and  he  is  always  willing  to  help.

ZX8 1  RESOURCES 


A  Tethered  Robot 


This  project  was  found  in  the  Noveiber  and  Deceiber  1986  issues  of  SINCLAIR  USER  and  is  suitable  for  both  the  2068  and 
the  ZX81.  The  original  article  was  written  by  Rupert  Goodwins  and  his  design  was  based  on  a  siiple  plat fora  with  two 
powered  wheels  and  a  caster,  you  could  easily  substitute  a  cheap  plastic  iotorized  toy  (one  that  is  powered  by  an 
attached  cable  and  handset).  Here  one  iotor  drives  the  rear  wheels  and  the  other  totor  turns  the  front  tires. 

The  project  consists  of  two  circuits  built  up  on  VEROboard.  The  first  circuit  and  board  layout  is  for  a  siiple 
Input/Output  board  that  plugs  into  the  back  of  the  computer.  If  you  already  have  an  I/O  board,  you  don't  need  to 
construct  this  interface.  The  second  circuit  and  board  layout  is  for  a  flotor  board  which  provides  the  switching  logic  to 
control  the  direction  that  the  iotors  will  turn  (the  layouts  are  done  on  graph  paper  that  has  the  saie  pitch  as  the 
holes  in  the  VEROboard).  A  ribbon  cable  between  the  interface  and  iotor  board  carries  the  control  signals  and  power  to 
the  iotors.  Note  that  the  interface  and  iotor  boards  will  not  control  the  speed  of  the  iotors,  just  the  direction. 

Construction  is  started  by  cutting  the  VEROboard  to  size  (25  x  36  holes  and  37  x  36  holes).  IMPORTANT  NOTE;  the  board 
layouts  show  the  bottoi  or  copper  side  of  the  VEROboard.  That  leans  that  the  transistors  and  ICs  are  being  viewed  froa 
the  bottoi!  Locate  and  cut  the  traces  larked  by  an  x  on  the  layouts.  A  perianent  larker  lakes  the  job  easier  to  catch 
listakes  before  you  cut.  Insert  all  of  the  juipers  before  you  load  the  components,  again  making  sure  that  you  have  the 
right  holes.  Use  sockets  for  the  ICs  and  be  careful  not  to  overheat  the  diodes  and  transistors  when  you  solder  thei  in. 
Check  both  boards  for  shorts  or  lisplaced  bits. 

Before  you  insert  the  ICs,  plug  in  the  interface  board  and  turn  the  coiputer  on.  If  the  coiputer  does  not  coie  up,  power 
off  and  check  for  shorts  or  lisrouting  on  the  lines  and  leads  coming  from  the  edge  connector.  If  everything  is  ok, 
insert  the  ICs  and  test  again. 

Connect  the  two  boards  together  with  the  ribbon  cable,  hook  up  the  switches  but  not  the  iotors,  and  try  the  following 
tests: 


2068  10  PRINT  IN  31; ■  ';: INPUT  '  ':60T0  10 

zxai  1  REM  xxxxxxxxxxxxxxxxx 

10  FOR  X=16514  TO  16519 
20  INPUT  A 
30  POKE  X,A 
40  NEXT  X 

100  PRINT  USR  16514; ■  •; 
110  60T0  100 


Input  the  following  lachine  code  ignoring  the  inforiation  after  the  seiicolon: 


219  31  ;  IN  A,  (31) 

79  ;LD  C,A 

6    0  ;LD  B,0

You  should  get  a  screenfull  of  255's,  which  change  to  223's,  239's  and  207's  as  the  switches  are  pressed.  If  you  don't 
get  255's  then  check  the  wiring  around  IC1  and  IC2  on  the  interface  board.  Next,  switch  everything  off  and  connect  the 
iotors.  Switch  on  again.  If  one  or  other  of  the  iotors  starts,  try  switching  on  again.  If  the  condition  persists,  check 
the  wiring  around  IC3,  the  area  around  the  transistors  and  the  diodes.  If  the  iotors  are  silent,  then  try  the  following 
tests: 


2068  OUT  31,1  one  iotor  should  start 

OUT  31,2  saie  iotor  should  reverse 

OUT  31,0  stops  iotor 

OUT  31,4  the  other  iotor  should  start 

OUT  31,8  reverse 

OUT  31,0  stop 

To  get  both  iotors  running,  add  the  nuibers  together: 

OUT  31,5  Both  iotors  running 

OUT  31,9  !•*  iotor  forward,  2"-  iotor  reverse 

OUT  31,10  both  iotors  reverse 

OUT  31,6  !•*  iotor  reverse,  2"d  iotor  forward

QL  JOTS  and  TITTLES  Page  i 

by  John  Juergens 

I've  been  corresponding  with  Hugh  Howie  for  the  better  part  of  two  years. 
During  that  tine  I've  mentioned  various  things  which  do  and  do  not  work  for  me 
on  our  Gold  Card  QL.    Hugh  suggested  that  these  should  be  shared  via  SINC-LINK. 

Our  QL  has  three  disk  drives:  FLP  1  is  a  5.25"/720K  drive,  FLP  2  is  a  3.5"'720K 
drive  and  FLP  3  is  a  3.5"/3.2M/ED  drive.  FLP  3  was  velcro'd  onto  the 
double-drive  case  which  houses  FLP  1  &  2. 

FLP  3  uses  only  5  volts  which  is  furnished  by  the  double-drive  power  supply.  We 
use  FLP  3  as  one  would  a  hard  disk  and,  as  such,  it's  very  handy  and  contains  a 
lot  of  stuff  I  would  have  to  look  through  other  disks  to  find  when  I  need  it. 
Like  Topsey,  it  grew  ...  and  grew  until  eventually  I  had  to  decide  what  to  save 
and  what  to  keep  on  it.  Again,  eventually,  that  process  will  have  to  be 
repeated  ...  and  repeated  ...  but  that  is  sort  of  the  way  life  is. 

If  you  believe,  as  I  do,  that  simpler  is  better  then  why  press  CTRL  &  C  when  one 
keypress  will  do  it?  I  use  the  British  Pound  Sign  &  tilde  key  as  I  have  yet  to 
find  aother  regular  use  for  that  key.  To  change  CTRL  &  C  to  the  BPS,  refer  to 
JBOOT,  below. 

If  you  use  Quill  you  may  find  that  after  some  amount  of  character  deleting  and 
re-arrangement,  the  screen  seems  odd  or  the  cursor  is  not  positioned  correctly, 
just  press  SHFT  &  F5.    It's  quick  and  straightens  things  out. 

Although  I  have  used  TaskMaster  and  bslieve  it  to  be  a  truly  great  programming 
triumph,  I  prefer  for  several  reasons  to  use  a  modification  of  Bill  Cable's 
Taskette  switcher.  One  of  the  problems  I  encountered  initially  with  setting  up 
Taskette  was  that  the  only  thing  that  would  stop  the  SuperBasic  portion  from 
multi-tasking  with  the  on-screen  application  was  to  let  SuperBasic  come  to  rest 
with  an  INPUT  command.  That  is,  INKEY$(-1)  would  initially  stop  activity  in 
SuperBasic  but  as  soon  as  one  hot-keyed  into  an  application,  such  as  Abacus  or 
Quill,  and  pressed  a  key,  it  would  trip  the  SuperBasic  INKEY$(-1)  and  off  the 
program  in  SuperBasic  would  go  ALONG  WITH  the  application,  slowing  both  down 
noticeably.  Worse  still  was  that  hot-keying  back  into  SuperBasic  would  result 
in  chaos. 

That  all  changed,  i.e.,  requiring  an  INPUT  command  in  SuperBasic  to  utilize  the 
Taskette  switcher,  when  I  discovered  the  extensl  file  in  the  QL-Exchange  suite 
recently  released  into  public  domain.  When  extensl  is  RESP'd  and  called  in  a 
BOOT  program,  not  only  does  it  stop  SuperBasic  from  multitasking  when  INKEY$(-1) 
is  employed  but  it  RE-WRITES  the  last  program  screen  automatically  in  response 
to  either  CTRL  &  C  or  a  POKEd  substitute. 

Macros:  I  think  that  macros  rank  right  alongside  the  eraser  and  Kleenex  in  the 
world  pantheon  of  great  inventions.  The  first  macros  I  came  across  were  the 
KeyDefine  group.  Later,  when  I  purchased  Turbo  Quill  +  I  found  to  my  surprize 
that  the  package  not  only  speeded  up  Quill  but  that  it  included  the  capability 
of  macro-making.  The  MOST  interesting  macro  of  TQ+  was  the  one  invoked  by  CTRL 
&  S  (S_Keydef)  because  it  was  a  START-UP  macro,  that  is,  after  Quill  loaded,  the 
macro  would  "play"  automatically  without  need  for  another/other  keypress(es) . 
This  occurrs  only  because  TQ+  actually  modifies  the  Quill  program  during  the  TQ+ 
installation  to  have  Quill  "request"  the  file  S_Keydef. 


SINC-LINK 


QL  JOTS  and  TITTLES 


Page  2 


Once  it  became  clear  that  macros  COULD  do  something  automatically  upon  loading 
one  of  the  Quill  suite  of  programs,  I  looked  for  many  years  for  a  macro  which 
would  start  Abacus  and  Archive.  Yes,  I  was  aware  that  the  "run  ..."  command  in 
Archive  would  start  one's  program  WITHIN  Archive  but  that  provided  no  help  in 
starting  the  "run  ..."  automatically. 

Initially,  I  believed  that  the  TSL  complement  to  the  QL-Xchange  group  provided 
that  capability  but  I  was  wrong.  Although  the  TSL  capability  in  the  PC-Four 
group,  for  IBM  compatibles  what  QL-Xchange  is  to  QLs ,  WILL  perform  a  start-up 
function,  the  TSL  capability  in  QL-Xchange  will  not;  that  is,  the  TSL  capability 
in  QL-Xchange  can  only  be  keypress-initiated  once  the  Main  Menu  screen  in 
Xchange  is  displayed  but  not  before. 

Then,  a  few  months  ago.  Dilwyn  Jones,  sent  me  something  he  threw  together  -  out 
of  the  goodness  of  his  big  heart.  To  make  it  work  he  used  part  of  his  Dilwyn 
Jones  Toolkit  -  a  remarkable  collection  of  commands  and  routines  for  a  truly 
give-away  price  -  and  (included)  a  procedure  called  QUEUE  which  he  had  lifted 
from  Quanta.  QUEUE 's  author  is  Simon  Goodwin.  QUEUE' s  essence  is  that  it  will 
send  the  contents  of  a$  to  WHEREVER  the  cursor  is  enabled.  This,  of  course,  is 
the  basis  for  an  application-  start-up  macro  using  a  switcher  such  as  Taskette. 

We  now  can  do  most  anything  we  wish  IN  Abacus,  Archive  and/or  Quill  PROM 
SuperBasic  starting  with  LOADing  them  to  running  Commands  or  Functions. 

With  this  article-on-disk  to  Hugh  Howie  I  have  included  two  files:  JBoot  and 
JBootl.  They  include  everything  I've  mentioned  above  and  are  lightly  REMark'd. 
Additionally,  included  are  the  machine  code  files  to  make  the  utilities  run.  If 
you  wish  to  use  them,  you'll  have  to  get  a  copy  of  the  file(s)  from  Hugh. 

QUEUE  is  run  with  my  procedure  Cue.  Cue  is  invoked  from  procedures  starting  with 
CueWP..  and  CueSS..  which  contain  the  macros  running  from  SuperBasic  but 
AFFECTING  Abacus  or  Quill  WHILE  actually  in  and  running  Abacus  or  Quill. 
Taskette  is  procedure  MTsk.

Kabenhavn,  7.7.93 

Dear  QL  user, 

At  last  we  succeeded  in  getting  the  XCHANGE  program  released  for  you,  the 
QL  user.  XCHANGE  was  programmed  for  the  THOR  based  on  the  standard  PSION 
QL  software.  Dansoft  paid  a  considerable  amount  of  money  to  have  an 
improved  version  of  the  standard  software  but  based  around  the  concept  of 
the  IBM  XCHANGE  version.  The  software  was  then  distributed  on  license  from 
PSION  as  the  standard  software  running  on  the  CST  THOR  PC  computer.  Three 
versions  were  made:  one  english  version,  one  danish  version  and  a 
QUILL-only  XCHANGE  version  in  danish  (sorry  QL-users!).  Around  1989  the 
production  of  the  THOR  computers  were  stopped  due  to  cash  flow  problems. 
Dansoft  and  THOR  International  stopped  the  THOR  business  a  year  later.  All 
excisting  services  were  moved  to  other  people.  The  Ritzau  news  system  (NB: 
please  refer  to  QL  WORLD  anno  1987-88)  is  still  running  in  various 
information  centres  like  the  danish  television  and  radio  stations.  Nobody 
had  at  the  time  any  idea  of  releasing  the  XCHANGE  software  to  the  QL 
users.  However,  Dansoft  knew  that  pirate  copies  were  around  running  on 
QL's  and  other  compatibles!  We  had  copies  of  it! 

In  early  1993  we  contacted  Hellmuth  Stuven  (former  owner  of  Dansoft)  to 
get  an  idea  of  the  status  of  the  THOR  XCHANGE  program.  He  informed  us  that 
he  paid  for  the  development  costs  and  an  exclusive  agreement  of  the  sole 
distribution  of  the  THOR  XCHANGE  software.  He  agreed  to  release  the 
software  to  the  QL  community.  We  now  realise  that  PSION  themselves  have  no 
objection  of  letting  the  software  flow  freely  among  QL  users  (the  letter 
printed  in  the  June  issue  of  QL-world) . 

The  THOR  XCHANGE  contained  a  minor  degree  of  software  protection  against 
letting  the  program  run  other  platforms  than  the  THOR  computer.  It  was  a 
simple  check  whether  a  'THOR  watermark'  was  present  or  not  (the  THOR 
serial  number  display  on  initialisation  of  the  computer).  If  no  watermark 
was  present  the  program  simply  displayed  'This  software  is  only  running  on 
a  THOR',  and  executed  an  infinite  loop  (the  program  had  to  be  killed  from 
another  source,  e.g.  SuperBASIC) .  The  software  protection  has  now  been 
removed . 


SINC-LINK 


THE  RELEASE  OF  XCHANGE 


In  addition,  we  have  improved  the  XCHANGE  program  in  other  areas: 

1.  XCHANGE  used  to  call  the  MODE  system  call  to  redraw  its  windows.  You 
already  know  the  effect  -  all  windows  below  XCHANGE  are  displayed 
momentarily.  If  you  have  a  look  of  the  old  PSION  boots  you  will  notice 
that  they  close  SuperBASIC  windows  #1  and  #2  before  execution  the  PSION 
program  to  prevent  the  'window  demonstration'.  This  has  now  been  fixed. 

2.  XCHANGE  (and  the  previous  PSION  quartet)  created  a  dummy  job  for  its 
workspace.  The  drawback  of  this  is  that  if  you  accidentally  kill  that  job 
the  mother  job  will  crash  (since  its  workspace  has  been  corrupted  due  to 
QDOS  using  the  memory  for  its  own  purposes).  XCHANGE  has  now  been  modified 
to  allocate  its  workspace  in  the  Common  Heap  Area  (dynamic  allocation/ 
deallocation)  as  any  job  usually  does. 

3.  The  old  PSION  quartet  had  no  active  cursor  which  had  the  effect  of  not 
being  able  to  activate  the  PSION  console  input  by  CTRL  C,  if  the  program 
had  been  executed  by  the  SuperBASIC  EXEC/EX  commands.  The  problem  of  that 
were  fixed  if  you  installed  the  pointer  environment  with  its  protected 
windows.  If  you  do  not  have  any  window  system  installed  in  your  QL,  you 
would  have  the  same  problem  with  XCHANGE.  However  we  have  modified  XCHANGE 
with  an  active  cursor  (but  not  visible)  to  prevent  that  problem. 

Unfortunately  all  THOR  XCHANGE  documentation  (based  around  QUILL  files) 
exists  only  in  danish.  There  is  still  a  chance  to  get  information  in 
english,  since  all  english  THOR  users  have  the  standard  THOR  manuals.  You 
should  be  able  to  contact  a  THOR  user  through  QUANTA.  However,  much 
incorrect  information  will  be  present,  since  it  was  written  before  the 
XCHANGE  program  was  finished  for  the  THOR  (the  XCHANGE  information  in  the 
english  THOR  manuals  were  based  around  the  IBM  XCHANGE  version  which  has 
more  features  than  the  present  THOR  version).  Do  not  despair,  dear  QL 
user,  since  you  still  have  the  online  help  (with  Fl).  Additional 
information  of  XCHANGE  will  be  found  in  this  document.  We  have  only 
included  the  information  that  cannot  be  read  from  the  XCHANGE  help  files. 
All  other  information  should  be  comprehendable  from  the  help  files. 

One  last  thing;  both  the  old  PSION  programs  and  XCHANGE  draw  their  lines 
around  menus  by  POKE'ing  directly  to  the  screen  memory!  EASEL  draws  its 
graphs  partially  in  the  same  way!  If  you  use  the  ATARI  QL-emulator  with 
the  EXTENDED  MODE  4  emulator  card  (780x280  pixels  in  mode  4)  a  lot  of  mess 
is  drawn  onto  the  screen  whenever  an  XCHANGE  menu  is  drawn  or  XCHANGE 
EASEL  is  active.  This  is  because  the  base  address  of  the  screen  memory  is 
lower  than  on  the  QL.  If  you  have  installed  the  QVME  card  in  your  ATARI, 
there  is  no  problem  since  the  video  memory  on  the  card  is  placed  at  a 
completely  different  address  (in  high  memory).  Since  the  menu  lines  is 
drawn  in  the  old  screen  memory  you  will  have  XCHANGE  running  perfectly 
without  the  menu  frames.  However  you  will  get  only  half  of  the  graphics  on 
the  screen  in  XCHANGE  EASEL  -  the  rest  is  actually  POKE'd  in  the  old 
screen  memory.  With  driver  release  E.30  you  can  use  a  command  to  activate 
the  standard  512x256  resolution  with  all  screen  output  directed  to  the  old 
screen  memory.  This  is  then  copied  via  the  fast  ATARI  blitter  chip  to  the 
QVME  card.  XCHANGE  will  display  everything  again  as  it  used  to. 

Executing  the  XCHANGE  on  a  QL  (or  compatible) 


SINC-LINK 


THE  RELEASE  OF  XCHANGE 


Since  XCHANGE  was  designed  to  run  on  a  THOR,  certain  things  must  be  obeyed 
to  be  able  to  execute  it  on  a  QL: 

1.  You  must  have  at  least  256K  expanded  RAM  in  your  QL.  XCHANGE  is  a  183K 
program  which  needs  minimum  64K  workspace. 

2.  XCHANGE  creates  a  workfile,  ,Psion_xch*  in  raml_  .  It  is  therefore 
needed  to  have  a  ramdisc  driver  installed.  If  you  have  a  Gold  Card,  an 
ATARI  QL  emulator,  or  a  QL  with  expanded  RAM  and  QRAM/QPAC2,  there  is  no 
problem  since  they  install  a  RAM  disk  on  initialisation.  If  you  do  not  own 
a  RAM  disc,  but  have  a  disk  drive,  you  can  execute  the  following.* 

FLP_USE  RAM    < ENTER > 

EXEC  RAM 1_XCHANGE    < ENTER > 

The  June  issue  of  QL-world  indicates  that  other  modified  versions  of 
XCHANGE  V3.90  exists.  If  you  should  get  any  information,  please  let  us 
know. 

If  you  should  have  any  queries,  please  contact  us  at  the  following

We  hope  that  you  will  enjoy  XCHANGE,  and,  it  is  your  responsibility  to 
distribute  XCHANGE  to  every  QL  user  you  know! 

Best  wishes  from 

Gunther  St rube  &  Erling  Jacobsen 


DID  YOU  KNOW?  

The  origin  of  the  terms  bug  and  debugging  is  thought  to  have 
occurred  in  1945  during  the  development  of  a  computer  called  the 
Mark  II.  A  relay  in  the  machine  failed.  The  cause  of  the  failure 
was  found  to  be  a  moth.  The  development  team  carefully  removed 
the  moth  and  taped  it  into  their  log  book.  From  that  time  on. 
when  the  computer  was  not  working,  the  development  team  members 
said  they  were  debugging  the  computer. 


DID  YOU  KNOW?  

The  keyboard  as  we  know  it  (QWERTY)  was  designed  in  the  last 
century  for  use  on  the  Remington  Typewriter.  The  designers  found 
that  it  was  too  easy  to  jam  the  hammers  on  the  typewriter,  so 
they  moved  the  most  commonly  used  keys  around  to  decrease  the 
typing  speed.  Several  alternative  keyboard  layouts  are  available 
but  few  people  take  the  time  to  learn  them.

DETROIT  AREA  BBS 

I  have  recently  heard  from  John 
Impellizzeri  that  he  and  Don  Walterman 
have  set  up  a  BBS  in  the  Detroit  area, 
and  that  they  have  a  linkup  with  Tony 
Firshman's  (of  TF  Services)  BBS  in 
England  to  exchange  messages  with  other 
QL  users  in  Europe. 

There  are  file  areas  with  plenty  of  the 
latest  public  domain  programs  available 
for  download.  Any  message  you  leave  on 
the  BBS  will  be  echoed  around  other 
BBS's  in  Europe. 

This  BBS  is  available  24  hours  a  day, 
300/1200/2400  baud  callers  are  welcome. 
There  is  no  cost  other  than  a  phone 
call  to  the  Detroit,  Michigan,  area. 

This  BBS  runs  entirely  on  a  Sinclair  QL 
and  is  called  "Qbox-USA",  and  can  be 
reached  at  (810)  254  -  9878. 

AN  800  NUMBER  BBS? 

I  have  also  heard  a  rumour  that  there 
will  soon  be  an  800  number  BBS.  It  will 
be  operated  by  Taylor  Penrose,  and  I 
understand  it  will  be  in  Florida. 

It  will  be  a  few  weeks  before  it  is  up 
and  running,  and  will  operate  from  1  AM 
to  2  PM  EST.     The  number  is  to  be:- 
(800)  942  -  6721 

You  are  asked  to  call  voice  before 
dialing  with  your  modem. 

Further  information  will  be  provided  as 
it  becomes  available. 

MIRACLE    in  NEWPORT  to  be  REPEATED. 

It  has  been  announced  that  IQLR  will  be 
holding  another  Miracle  in  Newport  on 
May  14th  of  this  year.  I  have  been 
told  that  Stuart  Honeyball  of  Miracle 
Systems  will  again  be  in  attendance. 
This  will  probably  be  the  North 
American  debut  of  the  SUPER  GOLD  CARD, 
utilising    the  68020  CPU. 


Reputed  to  be  three  times  faster  than 
the  Gold  Card  -  this  makes  it  about  25 
times  faster  than  the  original  bare 
128K  QL!  Four  Disk  drive  capability, 
24  Mhz.  32  bit.  RAM  of  3968  KB. 
Parallel/Centronics  port.  And  goodness 
knows  what  else.  Hey  mother  where  is 
my  check  book? 

Talking  about  check  books,  that  would 
appear  to  be  the  only  fly  in  the 
ointment.  The       cost       for  the 

SUPPER  GOLD  CARD  is  going  to  be  about 
£375,  and  with  a  Gold  Card  used  in 
exchange  about  £250.  Those  prices 
could  and  probably  will  be  changed 
before  this  gets  into  print. 

I  have  heard  that  Dilwyn  Jones  and 
family  are  coming.  Many  were  sorry  he 
was  absent  last  year.  No  doubt  he  will 
have  plenty  of  his  software  catalogue 
items  to  assist  you  in  getting  rid  of 
that  heavy  wallet! 

John  Impellizzeri  and  his  partner  Don 
Walterman  will  have  their  QB0X_USA  BBS 
in  actual  operation. 

Bob  Guilder  will  have  his  digitiser  in 
operation. 

Ron  Dunnett  of  QUBBESOFT  will  there 
with  his  Fastnet  QL  networking 
interface.  By  that  time  his  IDE  hard 
disk  interface  called  QUBIDE  might  also 
be  available. 

Al  Boehm  will  be  showing  his  cloud 
making  ideas  which  he  uses  in  his  job 
of  creating  cloud  patterns  for  showing 
on  TV  weather  charts . 

Paul  Holmgren  and  Frank  Davis  from 
Mechanical  affinity  will  be  there  with 
a  whole  stack  of  new  goodies.  I 
believe  they  are  trying  to  expand  their 
software  endeavors. 

Ernie  Richardson  is  returning.

News  -  and    some    QL    Library  Additions 

bj  Hugh  Bowie  Pagr 


It  is  anticipated  that  there  will  even 
be  a  German  contingent  coming  over  - 
but  this  has  not  been  confirmed  as  of 
this  date.  Perhaps  the  cost  of  travel 
might  be  too  much. 

This  year  the  show  will  be  held  in  the 
Howard  Johnston  Motel,  where  the 
facilities  should  be  a  vast  improvement 
over  last  year. 

Dinners,  Sunday  brunch,  get  togethers, 
are  all  laid  on,  add  what  you  want  to 
do  yourself,  and  this  should  be  a  great 
show. 

All  in  all,  it  looks  as  if  this  might 
be  the  show  to  see  for  this  year. 

It  is  a  great  pity  that  we  cannot  have 
a  QL  or  Sinclair  get-together  nearer 
the  centre  of  the  continent.  Just 
imagine  the  interest  that  would  create, 
when  folks  from  all  over  would  have  a 
better  chance  of  attending.  To  say 
that  the  QL  is  dead  is  not  bourne  out 
by  the  interest  being  shown  in  all 
parts  of  the  world,  and  by  the 
proliferation  of  new  improved  hard  and 
soft  wares  being  produced.  Today,  the 
QL  is  what  it  was  intended  to  be,  and 
there  are  not  many  computers  which  have 
withstood  the  test  of  time  as  the  QL 
has . 

CHEAP  MODEM 

There  are  some  2400  baud  modems 
available  at  a  very  modest  cost,  $8.95. 
They  are  uncased  and  require  a  $1.50 
power  supply  to  be  soldered  in.  They 
are  available  froml- 
Halted  Specialities  Co. 
Phone  1  800  441  5833 

The  modem  (an  EVEREX)  is  part  number 
14467,  and  the  adapter  and  its 
connector,  part  number  14041  costs 
$1.50. 

That   is   the  extent   of  my  knowledge  on 

those  modems . 


DKOPY  ~  a  Disk  Copier 

I  have  received  from  John  Juergens  a 
disk  copier  that  will  allow  a  disk  to 
be  copied  to  and  from  the  same  disk 
drive,  and  also  will  handle  the 
ED  drive.  Operation  is  relatively 
slow,  but  it  does  make  a  photo  image 
copy. 

Title:-  DK0PY_BAS 

To  copy  from  flpl_  to  flpl_  is  slow, 
and  it  takes  about  seven  disk  changes 
to  complete  the  task.  Of  course  it 
will  also  copy  from  drive  to  drive. 
There  are  certain  limitations  but  there 
are  many  who  will  be  able  to  make  use 
of  this  routine.  It  will  be  on  library 
disk  UTIL_2. 

It  requires  Gold  Card  and  TK2  to  be 
active.  It  was  designed  to  fill  in 
some  of  the  gaps  in  "DISCOPY"  which  is 
a  commercial  program.     DKOPY  is  PD. 

The  only  way  to  assess  DKOPY  for  your, 
own  use,  is  to  try  it. 

ZIP  /  UNZIP 

Zip/Unzip  is  a  file  compression  system 
which  is  mainly  used  in  BBS's  for  the 
transmission  of  information  in  a 
condensed  form,  thus  saving  phone  time 
to  say  the  least.  It  can  also  be 
useful  if  you  wish  to  send  someone  a 
lot  of  material  on  disk,  again,  a 
saving  of  postage  not  to  say  the  cost 
of  the  disks. 

Most  material  can  be  condensed  to  about 
half  its  original  size.  Large  files 
can  be  compressed  more  than  small  ones. 
A  BOOT  file  of  half  a  dozen  lines  for 
example  will  go  over  without 
compression,  but  a  long  file  of  a  few 
hundred  K  will  have  a  compression  rate 
of    sometimes    over    70%.  An  average 

full  disk  will  be  compressed  about  60%. 

The  ZIP  suite  is  about  650K  (UNZIPPED) 
and  if  you  ZIP  it  you  don't  have  any 
means  to  UNZIP  it!

Page  3 


The  version  in  the  library  is  version 
3,  and  is  on  Library  disk  ZIP_1 


NOTE 

The  following  files  are  on  C0MM_2  disk, 
and  are  in  ZIPped  form,  so  you  will 
require  the  ZIP_1  disk  to  make  them 
available.  As  stated  later,  those  and 
UNZIP  can  be  combined  on  the  one 
HD  disk  for  your  convenience. 


QeM  v  4.0 

QeM  is  a  Communications/terminal 
program  for  accessing  BBS's.  It  has 
ANSI  support  and  many  file  transfer 
protocols.  Requires  XPR  V2.10  files  to 
operate.  XPR  is  required  for  file 
transfers  with  QeM,  and  is  provided  as 
part  of  the  suite. 

QeM  is  by  Jonathan  Hudson,  and  the 
version  in  the  library  is  v4.0 

QTPI  vl.l 

This  is  a  terminal  program  for  the 
pointer  environment.  It  requires  XPR 
v2.30  (included  on  disk)  and  also  the 
pointer  environment,   (not  included) 

This  has  the  same  features  as  QeM,  plus 
some  new  ones.  Also  by  Jonathan 
Hudson . 

XTRICATOR  vl.4 

A  ZX81  emulator  for  the  QL.  many  new 
features.     By  Carlo  Delhez . 

SPECTATOR  vl.7 

A  Spectrum  emulator  for  the  QL,  also  by 
Carlo  Delhez,  and  this  also  has  many 
new  features. 

QLGIF 

Two  utilities  to   encode   QL   screens  to 

GIF  files   and  a  decoder   for  GIF  files 

to  QL  screens,  by  Carlos  Delhez. 


BormanDEV's 

Three  new  device  drivers  to  allow  a 
PATH  device  (similar  to  MSDOS,  SUB  to 
allow  a  subdirectory  to  pretend  to  be  a 
totally  separate  drive,  and  REDIRECT  to 
rename  drives  or  files  or  to  redirect 
I/O. 

DJEP 

A  Deskjet  Envelope  Printer.  A  small 
utility  by  John  Impellizzeri  to  take 
advantage  of  the  Hewlett  Packard 
Deskjet  printers  built  in  envelope 
feeder.  This  requires  TK2,  the  pointer 
environment,  and  the  QMenu  extensions, 
none  of  which  are  provided  with  this 
utility. 

OLTRM  232 

Another  terminal  program.  This  one  is 
much  simpler  than  QeM  or  QPTI .  V2.32. 
Has  ANSI  support  and  Xmodem  file 
transfer.        By  Jan  Brededbeek. 

****** 

The  above  programs  have  been  placed  in 
the  QL  Library,  and  are  available  to 
all  members.  It  should  be  remembered 
that  some  of  them  are  quite  extensive, 
and  that  considerable  free  memory  is 
required,  but  then  again,  most  of  them 
are  Communication  and/or  BBS  programs, 
and  if  you  are  into  that  aspect  of 
computing  you  will  probably  have  that 
memory  available. 

Except  for  DKOPY  which  is  on  UTIL_2, 
all  the  others  will  be  on  the  C0MM_2 
library  disk,  in  ZIPped  form.  You  will 
require  the  ZIP_1  disk  to  make  those 
files  available. 

The  C0MM_1  and  the  ZIP_1  disk  can  be 
combined  on  one  HD  disk.

QINDEX 


Qlndex  is  a  program  to  help  you  to  produce  sorted  indexes  for 
a  book  or  file.  Unlike  database-style  indexing  programs  where 
you  type  all  required  entries  into  a  list,  with  this  program 
you  can  load  a  plain  text  file  or  Quill  _doc  file  and  mark 
words  or  phrases  directly  to  be  inserted  into  an  index.  The 
program  will  add  these  to  an  index,  which  can  be  built  up 
from  several  text  file  (e.g.  if  a  book  or  manual  has  been 
written  as  several  chapters  in  separate  files). 

A  search  facility  is  helpful  for  finding  all  occurrences  of 
an  item  to  be  indexed*  Entries  with  similar  references  can  be 
automatically  combined.  There  is  an  on-screen  count  of  the 
number  of  entries. 

Once  the  index  has  been  prepared,  the  index  can  be  exported 
to  a  text  editor  if  required  for  tidying  up,  manual 
alteration,  etc  prior  to  printing. 

The  program  offers  a  choice  of  setting  layouts  suitable  for 
printing  in  text  pitches  from  10  characters  per  inch  to  20 
characters  per  inch,  effectively  determining  the  number  of 
columns . 

There  is  also  a  choice  of  layout  styles,  where  you  can 
separate  groups  of  entries  starting  with  different  characters 
with  a  blank  line,  and/or  insert  the  appropriate  letters 
above  each  group,  for  example.  Of  course,  you  do  not  have  to 
use  one  of  the  supplied  layouts  -  you  can  add  your  own  with 
the  ability  to  import  the  index  into  another  editor  to  do 
some  manual  alterations. 

The  program  is  Gold  Card  and  Minerva  compatible,  and  works  in 
Pointer  Environment  (which  is  supplied,  of  course),  so  that 
it  can  be  mouse  controlled  if  required.  For  those  without  a 
mouse,  it  can  also  be  used  from  the  keyboard,  of  course.  It 
comes  with  a  simple  to  follow  printed  manual. 

The  program  is  available  on  disk  only  (3.5  inch  or  5.25  inch) 
and  expanded  memory  is  required.  Toolkit  2  is  required, 
although  nowadays  that  is  built  into  almost  all  disk 
interfaces,  so  that  should  not  be  a  problem.  Cheques  / 
Eurocheques  /  Postal  Orders  should  be  made  payable  to  "Dilwyn 
Jones  Computing" .  Payment  by  credit  card  (Visa  /  Access  / 
Mastercard  /  Eurocard)  is  also  acceptable.  The  price  is 
£20.00
