Im currently making a basic Blasterball/Hardball type game as a learning experience before the big stuff, but it's been one problem after another. Currently I've been trying to convert my code into modules or subroutines so that my code is easier to work with.

However, I ran into a nesting error in the process. Here is basically the code I'm working with at the moment which gives me the error

+ Code Snippet

DO
   GoSub welcome
LOOP

END

welcome:
   ` Clear screen with pitch black
   CLS RGB(0,0,0)
   ` Generate centered text in middle of screen
   center TEXT 320,200,"welcome to:"
   center TEXT 320,225,"My Unfinished Program"
   center TEXT 320,250,"Programmed by Nesting Errors R US."
   center TEXT 320,275,"Press ENTER to continue, or SPACEBAR to exit"
   ` Refresh screen until user presses ENTER or SPACE
   REPEAT
      SYNC
   UNTIL RETURNKEY() or SPACEKEY()
   ` If user presses SPACE then exit program loop
   IF SPACEKEY() THEN EXIT
   ` If user presses Enter continue on w/program
Return

Any and all help is appreciated very much. Please help me out. I'm really stumped on this one. Thanks guys.

I've got DB Classic and PS Skillz and I'm not afraid to use um!

what's the problem with it?? it seems to work fine except that you didn't do the if returnkey() and if spacekey() stuff right because of course it doesn't do what it should when you press it. Basically all I can tell you is that you've made your code more complex than it really needs to be, and change your exit in your if spacekey() to end so it'll actually end the program.

this code is much easier

+ Code Snippet

sync on

   center TEXT 320,200,"welcome to:"
   center TEXT 320,225,"My Unfinished Program"
   center TEXT 320,250,"Programmed by Nesting Errors R US."
   center TEXT 320,275,"Press ENTER to continue, or SPACEBAR to exit"

do
   if spacekey() then end
`   if returnkey() then goto continue

sync
loop

Ok I changed my code to this:

+ Code Snippet

   DO
      IF RETURNKEY() THEN EXIT
      ` If user presses SPACE then exit program
      IF SPACEKEY() THEN END
      ` If user presses Enter continue on w/program
      SYNC
   LOOP

However, now I'm getting a "RUNTIME ERROR. FILE DOES NOT EXIST" on the line where I use LOOP

The point of the EXIT command was to EXIT the main program loop where the program would then free up system memory then end. After the Subroutine welcome the game would continue to level_one if the user pressed the return key.

+ Code Snippet

DO
   GoSub welcome
   GoSub level_one
   GoSub level_two
   ` etc. etc.
LOOP
Gosub delete_resources
END

I hope that shows what I'm trying to do a little clearer. What I don't understand is when I wasn't useing modules my code worked perfectly. Oh well,

I really hope someone can answer this. It's drivin' me nuts.

that looks fine, so I assume your problem has something to do with your routines theirself, maybe or another part of your code. It's hard to guess at all the possible problems without more code to look at. The only thing I can add is that welcome runs every loop cycle and maybe your tring for something different?

Well, I didn't think I would have to do this but hopefully it will allow you guys to figure out my problem. So here is the code I'm working with (below).

It gives me a Runtime Error at line 40. File does not exist at line 40.

Sorry in advance for the lack of comments, but you should be able to understand everything. It's all laid out in an orderly fashion.

In the loop the program is supposed to go through Subroutine hide_all_sprites then display the start_menu Subroutine. If the user presses Enter the program is supposed continue out of Subroutine start_menu and continue on through view_all_sprites and on to level_one.

I hope that makes sense. THANKYOU so much for your suggestions so far. Hopefully you will be able to solve my problem more easily now.

I'm actually using DBC but it still worked! Thankyou very much. I never thought to use Return instead of Exit. It just goes to show how much I still have ahead of me.

THANKYOU AGIAN
