THE WIZARD REVISITED In July's Help! section, there is an error regarding the program for
"Math Wizard," (Antic, April 1984). As noted in July, there is an
error in line 50 of the program listing, the 17th character should be an
inverse-video zero instead of the capital letter O. If you put in this
correction, the TYPO Table will read as published. However, if you
copied the original error (corrected above) the code letters at line ranges
5 through 60 will be CH rather than GA.
BUGGED NUMBERS
The renumbering utility in the July 1984 issue (Spaced Out Numbers)
has a slight bug. Surprisingly, it works fine on the XL's, but will
not recognize line numbers over 10,000 on the older Atari 400's and 800's.
The fix, for non-XL owners only, is to change line 31040 as follows:
31040 D=INT(VAL(C$)/INT(100^
(68-B(0))+1.0E-03))
The only addition is the +1.0E-3.

FEEDING YOUR FLOPPIES
The article "The Care and Feeding of Floppy Disks" (Antic, August 1984,
page 90), states that you cannot format the back sides of disks on a Rana
disk drive without punching an extra timing hole. Similarly, the
table (page 80) accompanying the disk drive survey in the same issue indicates
that you cannot format the back sides of disks with a Rana. This
is incorrect; the back sides of all disks can be readily formatted with
the Rana drive.
AMODEM QUOTES
There is an error in the instructions for AMODEM, (Antic, July 1984,
page 21). In the procedure for R-Receive (and others that include
specifying filenames), do not include quotes when you type in filenames.
ESCAPE FROM EPSILON
I ran "Escape from Epsilon" on my 1200XL and all I get is an orange
screen with a grey colored bar on the left side of the monitor screen.
What is the problem?
Vytas Banionis

This problem, as well as quite a few other errors, plagued a number
of readers attempting to run "Escape." We typed in the program from the
magazine itself. The TYPO Table matched and the program ran as it
was supposed to, so we know the program runs as published. There
are no errors in the program, and many who initially had problems entering
the program have succeeded in getting it to run properly. However in Line 500, POKE 559,0 turns the screen off,
so if an error is generated while the screen is blank, you can't see it.
Try changing the 0 to a 34. This will allow you to see the screen and watch
your progress. -ANTIC ED
PRINTER INTERFACE
In a recent issue, you stated that "the MPP-1150 printer interface
could be used with all models." Actually, if you own a 1200XL, you must
buy the MPP-1150XL interface, for the same price ($99-95).

The MPP-1150 works with all Atari models (including the 600XL and
800XL) except the 1200XL. If you own at 1200XL and have bought an
MPP-1150, return it to Microbits for a free exchange. -ANTIC ED
BOOLE'S LOGIC
There are two errors in one program line in
"Logic According to Boole"
(Antic, August 1984). Line 30 on page 51, which is the last line
on the page, should read:
Note that the penultimate operator is *, not -, and that there is only
one final right parenthesis.
TANKS FOR THE HELP!
In the June 1984 article on
Player/Missile Tanks, (page
53), line 1310 contains a character that looks like a semicolon. it's actually
a colon.
MORE WITH DOS
The article "Do More with DOS 2.0" (Antic, August 1984, page 31), describes
how to enhance DOS 2.0 to use with an Atari 1050 disk drive for increased
disk storage capacity. Disks formatted with the revised DOS are not
compatible with existing sector-copier programs for DOS 2.0, such as SCOPY
810. If you copy an "enhanced-density" DOS 2.0 disk with one of these
utilities, it will only copy the first 720 sectors, and DOS won't be able
to access the remaining sectors on the copy. The only way to copy
files with the modified DOS 2.0 is with the DOS menu's C function for multiple-drive
systems, or the O function for single-drive systems. Also, sectors
on disks created this way still only contain 128 bytes each-but there are
more of them.
WRONG COURTYARD
One of the BBS telephone numbers in "Let's Play Password," (Antic,
August 1984) is incorrect. The correct telephone number for the Courtyard
BBS is (312) 668-6272.
EVEN MORE DOS2
There is a typographical error in our August 1984 issue in the article
"Do more with DOS2," pages 32. Under Step 1, there is a line of instructions
that starts XI0. This should read XIO. That's a capital X,
a capital I and a capital O, not a zero.
NOTE AND POINT
In the April 1984 issue, "Update Disks with Note and Point" has an
error. Lines 410, 440, 470, 500, and 530 should each begin INLEN=LEN(USER$).
