Bill Russell tells SYNTAX he's creating some
new products for ZX/TS machines as well as
for the 2068. We can't say much at this
point, but at least one will be the kind of
software-hardware product that typifies G
Russell efforts—like the speech recognizer.

K-POWER TO FULFILL TSU SUBS
SPECTRUM MC ON 2068
Subscribers to ECC's ill-fated new
venture into North America, Timex-
Sinclair User, should have received
postcards by now, offering K-Power
to complete their subscriptions.
Scholastic Magazines publishes this
64-page slick magazine, which runs
Timex-specific programs, as well as
covering the Adam, Apple, IBM, TI,
Atari, TRS-80, VIC-20, and
Commodore 64 machines. Ad rates of
$6300/page limit ads from Timex-

TS USER NL (YAGSEE) FOLDS
Yagsee Publishing stopped producing
TS User newsletter with the Apr.84
issue. According to Derek Stubbs,
Timex's exit, followed by others,
left a market without new customers
as old ones moved to other machines
Renewals & subscriptions dropped, &
YAGSEE's informal survey projected
poor financial performance. But

SMART TERM II DELAYED
Upgraded performance for Westridge'
2050 modem will have to wait a tad
longer, but we do not know quite
when. The death of Stuart Lotwin
seems to have thrown the company
into chaos—phone calls unreturned,
information unavailable, and people
answering the phone who seem not to
care. All of us will miss Stuart,
and his rescue of the 2050 assures
his place in our memories. May his
family find solace in their grief.
NO NEWS ABOUT NO DEAL
No persons knowledgeable about the
bulk sale of Timex inventory or any
proposals from any potential buyers
were available at Timex. Doug
Smith verifies that all computer
hardware inventory is sold, and a
bulk buyer bought much of it.
The Ocean State Users Group reports
that they successfully entered and
used Spectrum machine code programs
from the UK magazine Your Computer.
Blockman, I.T., Lifter, and Doom
Church all went fine. Only the
program to copy Spectrum programs
failed. Contact Bob Dyl at 401-

45-PLAYER COMPUTER GAME UP IN MIAMI
American Software Technology is
testing an interactive, multi-user,
real-time game where you interact
with other players as well as the
computer. You can call Enternet at
305/866-8060 at 300 or 1200 baud.
You may pay by VISA, MC, or pre¬
paid deposit account. Currently,
the game is Fazuul, an adventure
game. Your object is to escape the
planet—you may team up with or
against other players. You pay for
the call plus 3-6 cents per minute
(depending on your modem speed).
ZX SPECTRUM SOLD IN CHINA
Sinclair Research, Ltd. will sell
600 48K Spectrum computers to the
computing and automation department
of China's North East Technical
College. According to Charles
Cotton, head of Sinclair's export
department: "China is a very
important potential market for us,
and one in which we are investing
considerable time and effort. This
deal represents an important
stepping stone to further
opportunities."
Wogen Engineering arranged the
contract and also demonstrates the
line of Sinclair computers at Wogen
offices in Beijing and Shanghai. A
consultant to the China trade, the
company also maintains a London
office and deals in metals, barter,
and counter-purchase deals, with an
emphasis on high-technology.
Sinclair will supply a library
of introductory programs including
microPROLOG and LOGO. Graduate
researchers at the college will use
the Spectrum as an effective, low-
cost means of learning BASIC skills
TIMEX TECH MANUALS SHIPPED
Timex shipped its initial stock of
photocopied 2068 Tech Manuals and
has orders for its scheduled print
run. A few orders were returned by
mistake. Re-order—the print run
will be expanded. Delivery to
Timex is scheduled for 15 August,
so you will not get your copy until
3-4 weeks after that.
MAGGIE BRUZELIUS LEAVES SINCLAIR
Facing an offer too good to refuse,
Maggie became Director of Marketing
for Alpha Software (Burlington, MA)
One of the few growing software
houses. Alpha sells an integrated
package with database, spreadsheet,
word processor & communications for
IBM PCs, JRs & XTs "We're steaming
full ahead on business productivity
software. Electric Desk is easy to
use, comes on one disk, needs no
extra memory & sells for only $345.
It really is neat!" says Maggie.
VEN PQR REPORT
Byte-Back has nearly cleared up its
backlog of 2068 modem orders, but
is shipping only the dumb terminal
software. Jerry Minchey hopes to
get the smart software out quickly,
and will send the tapes in a
follow-on shipment. The current
version is a dumb terminal with
printing capability.
Ray Kingsley of Sinware believes
that some of you may have purchased
bootleg copies of an early version
of HOT-Z with a bug in it. Ray
says he is the only legitimate
seller of HOT-Z. If you purchased
stolen goods, seek a refund from
the seller and reinvest with the
program owner. A simple offer to
provide postal inspectors with
evidence of the transaction will
work wonders if you meet resistance
We received an allegation from
Canada so startling that we dare
not print it. Suffice it to say
that Timex software does not come
in baggies with photocopied
documentation and brand-x tapes.
SYNTAX suggests that you do no
business with stores that offer you
such merchandise.

DATASAVE—FILES WITHOUT PROGRAMS
8K/16K
DATASAVE allows you to save a
selected portion of memory to tape
and then load it back again to any
part of memory. Loading code with
DATASAVE does not (of necessity)
write over the program that you are
running, so a program can load data
from tape, manipulate it, and then
save it back to tape.
DATASAVE's machine code (MC)
resides in the first REM. To make
the REM, type listing 1 exactly as
shown. Note that there are a total
of 155 A's, and the last line of
REM should have four A's.
If the Syntactic Sum checks
out, RUN the program and enter the
numbers from listing 2, reading
left to right. When the program
stops you should see a screen as in
listing 3. Skip the next paragraph
if the Syntactic Sum agrees with
the one shown following listing 3.
LISTING 1
LISTING 2—POKE TABLE
If you have a wrong Syntactic
Sum, add lines 1000-1040, shown in
listing 4. RUN 1000 and check the
data on the TV screen (ignoring the
final five numbers) against listing
2. POKE as appropriate to correct
data, or if you need major repairs.
re-RUN the whole program. Now test
for the Syntactic Sum shown at the
end of listing 4.
Delete all line numbers except
1. The Syntactic Sum for line 1 is
18612. As a precaution, you may
want to change the line number to 0
with POKE 16510,0. This prevents
accidentally editing the REM. The
POKE makes the Syntactic Sum 18611.
DATASAVE works much like the
ZX/TS's normal SAVE and LOAD: it
uses ROM calls when possible. Set
your recorder as you would normally
for SAVE or LOAD. No "program
name" is used, so none is required
to SAVE data, and the first data
found during LOADing will be read.
Look at listing 5 to see how
you can use DATASAVE. Variable S
defines the start of your memory
area to SAVE or LOAD: E sets the
end. After defining S and E, you
SAVE data with RAND USR 16514 or
LOAD data using RAND USR 16543.
Change S and E as you wish. The
sample in listing 5 SAVES and LOADS
the top 1024 bytes of a 16K memory.
Set RAMTOP below this area.
LISTING 5 (append these to 1 REM)
Three error reports can occur
when using DATASAVE:
Report 2 - S or E not defined
Report B - S or E out of range
(0-65535)
Report D - BREAK depressed
When you use DATASAVE its Syntactic
Sum changes. Restore it to its
original value with POKE 16667,0
and POKE 16668,0.

DEAR EDITOR
I'm quite put out.
You say you're going to charge
$48 for SYNTAX because of increased
costs. You point out that Time Inc
charges $48 for their 12-pager, and
this justifies your decision.
Time's newsletters are about
IBM and Apple, which cost far more
than ZX/TS computers. Time will
charge "what the traffic will bear"
My total costs to subscribe to
ZX Computing (156pp) are $24.33 for
six issues & Sinclair User (148pp)
costs only $43.56 for 12 issues.
Why should we pay you $48 for
12 twelve-page newsletters?
John Sampson, College Pt. NY
John, I personally talked to Time's
newsletter publisher about your
point. Not so. The traffic would
have borne far more—$48 is the
lowest price Time considered.
You pay $48 for value. Here's
what 7 survey respondents said
about the value they've received.
"As a newcomer to computers 2
years ago, I needed all the help I
could get and found that SYNTAX
(recommended to me by a freind)
pointed the way to a lot of places
I would not have found otherwise."
"I appreciate your avoiding
the high gloss and continuing with
high quality instead."
"It is virtually impossible to
assign a dollar value to your
publication, but some of the
explanations and examples in your
articles helped me to get my
present job, which is obviously
worth a great deal to me."
"I learned a tremendous amount
from SYNTAX & to date I've learned
more about computers from SYNTAX
per $ spent than any other computer
publication I have bought."
"Each good item is worth the
price of that month's issue."
"Please do eveything possible
to continue publication. I would
happily pay 2-3 times the price if
needed to cover lost income from
faint-hearted supplier's and
manufacturer's advertising."
SYNTAX is going the way of the dodo
it will not emulate the phoenix.
Anyone who has nerve to charge $48
a year for the junk that has been
printed in the past nine months
deserves to fold. If you had a
decent newsletter that would
attract advertisers there would be
no need for a 70% increase.
Clifford Efaw, Morton, WA
Courage is the most important
virtue. Without it, no other can
be consistently practiced.
Ex-advertisers owe SYNTAX and
SQ $22,690.10—and we switched to
pre-pay in Jan.83! All companies
on the Apr.84 list were asked to
advertise, you see the results.
Those who get $48 in value
from SYNTAX should have the chance
to keep on getting it—KO.
InfoWorId's news page carried a
report about TimeStar and the Timex
Sinclair Computer. Synchro-Sette
carried a similar artcle in March.
Your publication was quick to
denounce such reports as unfounded
rumor, and even to assert that
Timex was not negotiating or had
received no proposals. It seems
interesting that the last major
publication for Timex Sinclair
Computers can not find out
information that a magazine like
InfoWorld is able to obtain.
It seems to many of us that
you would better serve your own
interests, as well as your readers,
if you would investigate this
possibilty fully and encourage Mr.
Higgenbach (sic) instead of
throwing cold water on such a
possible deal.
Lonnie Kendall, Reidsville, NC
I believe in the stance taken by
news stories in SYNTAX—KO.

Programmers who want to alter
the Westridge Modem software for
ZX/TS machines must first POKE some
locations in the REM line to avoid
crashes. Here's how:
LOAD the TS1000 software.
At the 0/0 report, type:
POKE 16529,149
POKE 16530,14
POKE 20264,118
Now you can add BASIC lines.
The authors of the modem soft¬
ware altered the pointers defining
the length of the REM holding the
code. Thus, when a user tries to
add additional lines, the program
crashes. The POKES correct these
pointers and place a 118 (ENTER) at
the end of the line. When the
computer sees this line properly,
new lines can be added.
Also, Westridge uses port 115d
for data and port 119d for control
of the 8251 serial chip inside.
Thomas B. Woods, Jefferson NH
Is there a way to reset ZX/TS
computers and retain the contents
from 16k-RAMT0P after a crash?
Also, where will I find ways
to use extra keys to get shifted
functions or FUNCTION operations
with single keystrokes?
Bill Jones, Panama City FL
SYNTAX knows of no simple way to
alter the reset scheme to save the
main memory area. Also, it might
do no good to do so — how will you
know the state of the machine?
You add shifted key functions
with diodes (SQ Winter 82 p.29) or
ICs (Mar.81 p.7) or double-pole
switches (Jan.83 p.10). To do the
functions, you need 2 keystrokes—
one to shift mode, the second to
select the specific operation. You
build the mode selector as shifted
enter or 9, then use either the
primary key or a specially marked
one to make the second stroke.
McGraw-Hill's new book. Beepers ,
shows an opto-isolator scheme for
functional keys & a CAPS lock—KO.
I am surprised that you stated
that there was a bug in my COMPILER
when I also sent you a correction
to that bug. The correction
probably did not arrive in time for
publication, but please print that
the bug has indeed been corrected.
The review placed very little
emphasis on the ability of COMPILER
to handle strings and very little
was mentioned of the Z80 ASSEMBLER
that comes with COMPILER.
I think most readers will be
pleasantly surprised if they buy
the compiler. It is not as user-
unfriendly as you make it seem For
one thing, you can run most pro¬
grams in BASIC prior to compiling
This helps to de-bug programs.
I don't know what you mean by
"display poor"....
John Richard Coffey, JRC Software
Scottsburg, IN
Your correction arrived on 5 July,
the issue was already on press. We
review the product we have, not the
one the supplier promises. SYNTAX
reviews only production versions of
products. As you say, there was a
bug. Years ago KO heard Dr. Harlan
Mills of IBM say there is no formal
proof that the last bug has been
found—you can never know your code
is bug-free unless you use methods
that generate bug-free code. Most
experienced programmers know "where
there's one, there are many."
SYNTAX reviewed only COMPILER,
as the first and last paragraphs of
the review emphasize. We therefore
have no comment on the assembler
other than to note that you sent us
2 corrections to that program, too.
Most does not mean all. If my
program doesn't run, how do I know
if it's my mistake or yours? Our
program ran in BASIC, but not after
compiling. If we use one of your
non-standard BASIC constructs and
it fails to run, what then?
"Display: Poor" means error
messages just print on the screen
without formatting or organization.

LINESUN—8K/16K
Locating errors made in typing
from printed listings is easy when
they include a checksum for every
statement, and you have Linesum
loaded. It displays, line by line,
any BASIC present with line numbers
below 9000, & displays the sum of
the line's bytes. Add the line
sums to get Syntactic Sum.
Linesum's flexibility surfaces
with use. You LOAD Linesum first,
then after typing in a program line
you RUN 9000 & use the edit option
to fix errors or type another line
before returning to Linesum. That
way you check every program line as
you type it. Use the quit option
to free the computer to calculate,
and reenter Linesum at the point
you left it by typing GOTO SUM.
Long programs may be finished
piecemeal: if you tire, "quit" &
SAVE your partial program. LOAD it
later & take up where you left off.
If you get an inspiration and want
to try a BASIC routine while it's
fresh in your mind, do it. Lines
9536-999 are your work area. Don't
even clean up: test programs in
this area vanish when you erase
Linesum. With a merge utility, you
can type your new program, and only
append Linesum if the Syntactic Sum
indicates you have made a mistake.
Once you start Linesum do not
use RUN until you are all finished
with Linesum. Do GOTO SUM instead
to avoid killing variables.
To make your copy, LOAD your
Syntactic Sum tape, then type in
Linesum. Don't type the checksums
or the GRAPHICS 5, they aren't part
of the program. Syntactic Sum at
this point equals 35581. If you
get a different number, find and
correct any typing errors. Put
your ZX/TS in FAST, then SAVE this
version to a scratch tape.
Next, RUN Linesum on itself,
verifying each line in turn. The
Print option stops at each line—
the Lprint option runs by itself.
Add 1 REM with 22 placeholders
Next, RUN 9505, to load the MC
(machine code) into the Line 1 REM.
Enter all numbers on the POKE list,
then a STOP to exit the loader.
EDIT Line 1 to line number 9490.
Now edit line 9325, changing
9999 to 9000. Linesum will no
longer work on itself, but only on
program lines below 9000. The new
Syntactic Sum will be 38824. RUN
linesum to get the result shown:
Delete line 1. SAVE the
program to tape for future use. At
this step, Syntactic Sum is 36230.
Leave Linesum loaded and type
in the program "DATASAVE" shown
on page 5 of this issue. You won't
be able to get a correct Syntactic
Sum using the standard Syntactic
Sum program now, as Linesum is also
present, so do RUN 9000.
Now you can step through the
typed-in program 1 line at a time.
When the displayed checksum differs
from the printed one, use the edit
option to switch to normal BASIC
listing at the current line. Find
& EDIT the error, then do GOTO SUM
to go back to Linesum for a display
of the edited line and new checksum
After everything is fixed and
your line checksums agree with the
printed ones, you reRUN, using the
LPRINT option to get a LISTing with
linesums and the Syntactic Sum.
turn to p. 10

9
When you finish, erase the
entire Linesum program above 9000
using: GOTO 9485 & 9000 ENTER.
Linesum is menu-driven with 3
options after each line display:
Next Line, Quit, or Edit Current
Line. At the beginning, you choose
screen or printer output. At the
end of a screen session you can
examine the Syntactic Sum.
Lines 9485-500 erase Linesum.
Line 9485 gets the address of the
next line. The relocatable machine
code routine in line 9490 computes
the Linesum program length (from
9000 to the end of BASIC program
area) and stores this number minus
4 in the text length bytes of line
9000. When you delete line 9000,
all of Linesum disappears.

OUR POLICY ON CONTRIBUTED MATERIAL
SYNTAX invites you to express opinions related to any Sinclair or Timex com¬
puter or peripheral, or the newsletter. We will print, as space allows, letters discuss¬
ing items of general interest. Of course we reserve the right to edit letters to a
suitable length and to refuse publication of any material.
We welcome program listings for all levels of expertise, written in either Sinclair
BASIC or Z80 machine code. Programs can be for any fun or useful purpose. We
will test run each one before publishing it, but we will not debug programs; please
send only workable listings. Programs submitted on cassette can be tested more
quickly and with less chance of error.
In return for your listing, we will pay you a token fee of $2.00 per program we
use. This payment gives us the nonexclusive right to use that program in any form,
world-wide. This means you can still use it, sell it, or give it away, and so can we.
We will consider submissions of news and hardware or software reviews. Please
keep articles short (350-400 words). Again, we reserve the right to edit accepted
articles to suitable length. We will pay 7 cents per 6 characters, including spaces and
punctuation, for accepted articles.
When you send in articles for possible publication in SYNTAX, please include
the following information:
• How to operate the program, including what to input if it does not contain
prompts.
• Whether you can run the program over again and how.
• How to exit the program.
• The Syntactic Sum (program published in June 81;
send SASE for a free copy).
• What RAM size program requires.
• What ROM program uses (8K, 2068, Spectrum).
• For MC programs, what addresses must change to relocate the code and what
ROM calls are used.
We pay for this explanatory text at the same rate as we pay for articles in addi¬
tion to payment for the program itself.
