Here's my problem.
When I launch my game.exe then load my rpg file the game starts. The new game script load but then for strange reasons I've got the following message (the error code 9) As the errors occurs as my rpg is loaded I think it can be qualified as an runtime error.

Here what's the message says :

"Subscript out of range" means that an array index is too high or too low in QBasic somewhere. That is, you're trying to access the 100th element in an array of 10, for instance. More likely a negative index, I'd suspect.

Was this the error we were getting with the enemydata thing when the enemy number was more than 102? There's a thread about it around here somewhere. That particular problem has been fixed since Rusalka.

The address doesn't really mean a lot, sadly, so it would be quite difficult to trace back to a plotscript command.

Hmmm, must be the heap problem.

I forgot, if I fixed it before the release or after the release of rusalka.... wait it was after the release. So ye, it still stays there.

Sorry about that.

ok, try this later build of game.exe, see if you see the same problem.
by the way, this is in no way the official release.

Ok! I've made a test with the ysoft_entertainement's game.exe version.
The bug still happens (error code 9 exactly at same address). That means the heap problem is not what make bug my game which is a good thing to know.

So we can deduce that the bug is certainly due to the array index which is too high or too low in QBasic somewhere in the code of the game and the problem become serious as hssed.exe compiles.

So can somoene explain me how do I check the array index values ?? (Feel free to give many many details because I've never done that before)

Thanks very very much for the help and for answering so soon!

I would like to point out that the subscript that is out of range is not in the plotscript. It's in the engine somewhere.

Those error messages are almost always useless. To find you problem, we would have to look at your newgame script. could you please post it?

Also, exactly when does it crash? After you click New Game and the screen fades out? Anything at all happen before it?

You are right, its not heap problem(arfenhouse works with my build). so ye, we need to see your script before we can squash this bug.

and by the way, error code 9 means that the program tries to open same file twice. so the bug should be somewhere in the command that accesses the internal files.

Actually, it's quite legitamate to open a file twice. You just can't open a file for writing twice.

Further, why is the error message "Subscript out of range" if it's an I/O error?

As requested, I've posted the script. The game crashes as the teleport
to map (1, 84 ,63) command is executed. By crashing I mean that a windows with the message error code 9 appear. The only thing that left me to do after the game crashed is pressing a key and then click on the cross on the top right corner of the windows.

I wanted to say of course "if I were you I would write the code this way, it would be more EASIER for hssed to compile".

Anyway this comment (# Ce script dÃ©finit la premiÃ¨re partie de l'introduction du jeu. ) is written in french my mother tongue means #this cript contains the commands for the first part of the introduction of the game.

Another thing that may also be useful to know is that Hseed take about 7.2 seconds to compile my script. Tell me if that's too much!

Special thanks to player one for noticing this huge mistake
in the code. On my side I've noticed that I had put 2 lock hero commands.
I also deleted the useless resume box advance command. (I didn't have suspend it
at the beginning of the script. Unfortunatelly all this didn't have effects
on the bug. I've also made test using the debuging key (pressing F12
as the game plays) but nothing special appears.

I think I know where the bug may come from. I've certainly made
something wrong including the while loop in game code lines.
I'm quite certain that's the reason why the game bugs; because the bug has started
just after I include the while loop in my code.

That would also explain why the program tries to open same file
twice... so the bug should be somewhere in the command that
accesses the internal files for the second time. The fact that it happens
just before the main hero teleport would be due only to strange Qbasic coding.

As a matter of fact with my first tests with the while loop the same bugs
happened but a little bit after, as the Npc 16 (Luna) was appearing at the
bedroom entry and tried to go towards Usagi's chan bed.(That's what's
Luna is supposed to do in the game intro)

By the way could somoene tell me

1) What does I and O stand for in "I/O error"?
2) As the error may be in the command that accesses the internal files how can I check them?
and more important how will I notice them in the QBacic code which can be messy.

Anyway thanks again for bug reporting and also for anwering so quickly. I have put
a copy online of my rpg and hss files so feel free to ask for the links (or for other scripts that may contains)
My game intro is made of 3 scripts intro1 intro2 and chapter1 (at the end of which the extended
keyboard launch with a global loop) so the bug may also be in one of those other three scripts.
Good luck to all in making your games!

Can you post the link to your game?
