QUESTIONS AND ANSWERS
Neiman 06111
On some programs where I would
like to make a few changes, such as a
device number, is there any way to
make the change permanent on the
Loadstar disk, or must I list and
change each time?
>There is a way to make the change
permanent. Here's how you can do it:
1. LOAD the file you want to
change. You do this with the
common LOAD"filename",8
2. LIST the program and make
whatever changes you want.
3. Lastly, we have to save your new
version back onto the disk. To
do this, do the following with
the disk in the drive:
OPEN 15,8,15
PRINT#15,"S0:filename"
CLOSE 15
SAVE "filename",8
Be sure to use the same 'filename'
throughout this process.

Can a picture made with the KOALA
PAD be loaded on by DOODLE? Is there
a program I can type in that will
print out my KOALA PAD picture on to
my 1525 printer?
>There are rumors that KOALA is
working on a program that will allow
you to print-out your KOALA pictures.
Until then... We do not know of any
programs currently on the market
that allow you to transfer KOALA
pics to DOODLE pics. We have seen
one program, in the alpha-test form,
that permits it. However, KOALA pics
are in Multi-Color format and DOODLE
pics are in Hi-Res format. The
result of the transfer between
formats is pretty weird.
Is it possible to change the name of
my disk? If so how?
>Yes, it is possible. There is a
header changer program on Issue #7 of
LOADSTAR which will make the
technical work easy for you! Or, you
can change the name by altering bytes
144-161 of Track 18, Sector 0.

For some reason, there has been no
music on the last few issues of
LOADSTAR that I have received. In
Paperless Pages and Influx, there is
nothing but silence. Did I receive
defective copies?
>Our copies of the last few issues
have music on them, so you might want
to check out your SID chip. There
may be something wrong with it. You
also might try running some other
programs which have sound and see
(uh, hear) what happens. To make sure
that you will have music in LOADSTAR,
be sure to start by either loading
STAR or '!'. If you start any other
way, the music may not load properly.
If other programs give you sound and
music, you did get a defective disk.
We'll gladly replace it free if you
return it to us.
I have an OKIMATE 10 color printer
which has proven to be very useful
in helping print out beautiful color
pictures, some of which are from
LOADSTAR. But there is a small pro-
blem. You see, a disk comes with the
printer which allows me to print
pictures that are drawn on almost any
major graphics program (KOALA, DOODLE,
Chalkboard, etc..). This program works
fine when printing a LOADSTAR pixel
page, if I can figure out where the
picture was drawn. The way the
program works is that it searches for
the specific format that each program
gives to its pictures. Thus, it
is unable to recognize Koala pictures
on LOADSTAR that have been 'packed'.
Is there any way to 'unpack' a picture
and then resave it so that this
program will recognize it? I'm really
interested in finding a way so I'll
take any suggestions.
>After the picture is unpacked, say in
the PIXEL PAGE section of the
magazine, you may attempt to do a
binary save of the normal areas for a
KOALA picture (Hi-res, Color Ram, and
Screen-Color). There is a program
on Issue #1 of LOADSTAR called
BSAVE which should help you to save
these areas.

I just bought SIMON'S BASIC and want
to use it with TINKERTOOLS and EFIG on
LOADSTAR #10. I need some help. When
I load EFIG and merge it with
TINKERTOOLS, I get a BAD SUBSCRIPT
ERROR line 61 when I attempt to run
it.
>First, LOAD EFIG. Next, MERGE
TINKERTOOLS. If you RUN at this
point, you get your BAD SUBSCRIPT
ERROR. To fix this, simply change
line 500 to be line 0 and make
line 502 be line 2. Delete lines
500 and 502. Now the program should
work fine.

HELP! HELP! HELP!
When entering my FEEDBACK, I get an
an error and am dumped back to BASIC
after about 300 lines. What am I doing
wrong? Have I filled the BUFFER?
>That's exactly what you have done!
The Starline text editor has a
capacity of 300 lines. Any attempt
to enter more that this crashes the
the program (Sorry... we're working
on expanding the file capacity.)

Is it possible to get more than
eight sprites?
>Yes! To get more than eight sprites
on the screen, you must use a complex
screen raster interrupt routine. Ick!
The idea is to compare the TV raster
with a location on the screen. When
the raster is equal to the position,
you change sprites. Since the screen
raster is so fast, your eyes never
really see the first sprites go off
or the new sprites come on. Needless
to say, this is a very complicated
idea. Who knows, we may do a
tutorial based on it!
What is a good book and/or assembler/
dissasembler for a beginner?
>In the way of books, we would
recommend Jim Butterfield's book
'Machine Language for the Commodore
64 and other Commodore Computers'.
It is published by Prentice-Hall
Publishing Company. It covers every-
thing from the architecture of the
microcomputer to every form of
addressing. Not only is it a good
learning aid, but the back contains
many appendices which will help you
in your further attempts to master
assembly language.
In the way of assemblers, we would
recommend MERLIN, by Glen Bredon. It
is published by Roger Wagner
Publishing. It allows easy assembly
of your source files. You can save
the source and/or the object code.
MERLIN also includes a disassembler
called SOURCEROR.

I heard about Donna's checkbook
program and would like some more
information on it.
>Donna's checkbook program appeared on
Issue #3 of LOADSTAR. The program
allows for outstanding checks and
outstanding deposits. The program
allows you to enter your information
along with appropriate dates. The
program will then allow you to try
and balance your checkbook.
