STOS PROBLEM PAGE
=================
9th January 1994
Hi STOSSERS! My name is Martin Cubitt and I have been asked
to help you with any STOS problems you have, basically
coordinating the question and answers that YOU send in. I will be
able to answer some of the queries but there will inevitably be
some problems which I cannot help with. You queries may be
modified or shortened but the gist of your problem or answer
will remain.
Please note that although STOSSER is preliminary a STOS user
disczine we will also try to answer any general ST problems you
may be encountering.
If you wish to send in a question or an answer then please
send them to me:-
Martin Cubitt
14 Deepdene Avenue
Rayleigh
Essex
SS6 9LG
England
I regret that I can only enter into personal correspondence
if a stamped addressed envelope (and disc if necessary) is
included.
Please state if you want your name and address printed. This
enables other STOSSERS to get in contact with you directly.
However, if you do sort out a problem outside of STOSSER please
write to us and let us know the solution.
I shall be giving every problem a problem log number and the
problems will remain on STOSSER until a solution has been found.
This way you can reference a problem by problem number rather
than saying "the one about the sprites colliding...". In fact these
problems will stay on this column for sometime to give people a
chance to see the problems and solutions which occurred before
they got their first issue of STOSSER.
I have now started to purge old solved problems off the
problem page to stop it becoming oversized. Of course back
issues of STOSSER contain these problems.
For the record, the latest verion of the EXTRA extension
can be obtained from me (send a disc, pref not blank) at the
above address.It is PD and the latest version is:
EXTRA extension version 1.91
----------------------------
Well that's the introduction over with, let's get down to
some serious stuff...

and get out.BUT YOU ALWAYS have to get back to the castle to find
the other doors,once you get out the computer loads a new map in

Problem: 17
Keefy has written with a problem. He would like to know how to
load more than one packed picture into a memory bank rather
than a separate bank for each picture, and how to retrieve them
once this is done.
Solution to problem: 17
I have included (in a folder PROBLEM1) a number of files which
answers your question. There are two programs. One reads in all
the memory banks and then saves one big one. the second program
actually makes use of this big bank allowing you to select
pictures within it.
I believe the programs are fairly simple and with minor
alterations should suit most people.

Problem: 18
Jason Dale has written querying if their is a reliable means of
checking a disc is write protected to remove the chance of a
virus spreading.
Solution to problem: 18
I have included (in a folder PROBLEM2) two programs.
One uses the EXTRA extension command "write protected" which I
have to admit is not 100% sure to work because of the
strange way Atari's operating system changes from machine to
machine. However a second program is included which uses the
rather crude method of attempting to write a file (with no
data) to the disc. If there is an error (disc protected) then
the program continues, happy that the disc is write
protected. However, if the file saves, the program deletes it
and issues an error message asking the user to write
protect the disc and press a key when all is well.
We would encourage anybody to write in if they have any other
methods of checking if a disc is write protected.

Problem: 19
Marcus Platt would like to know how to use the hardware
scrolling commands which come with the STe extension.
Solution to problem: 19
I agree that the manual assumes that the user knows more than
the average programmer when it comes to using this
excellent extension.
The scrolling commands use a large playing field made up of
a number of screens. A program (CRTSTESCR/CRTSTESC2) must be
run to create this playing field. Because it contains a
number of screens the size of the playing field can become
quite large.
To compliment a previous query on the subject of this command
I have included a set of files in the folder PROBLEM3. Only
one file is missing but is created when you run CRTSTESC2. This
is the same as CRTSTESCR but allows packed pictures to be used
instead of just NEO's. Eight pictures have been included. The
file created is a massive 256,256 bytes so have plenty of
space available!
The advantages of the extension can be seen when running the
program STESC.PRG (once the large data file has been created)
in the enormous speed improvement. For once you end up in the
situation where you need to slow the scrolling down!
