I just wrote a presentation for a school project in DBP.
The thing is that the computers at my school of course have inferior DX versions; however, they seems to be able to run DX7.
Therefore, I figured that I could rewrite the source in DBC; shouldn't need to be changed that much.

Now though, apparently there are no such things as global variables, constants etc. in DBC.
How the heck to go around that?
I don't really feel like making every global variable an array :/

Suggestions, please

I think tdk has some tuts on that, like he does for everything.
Give me a while since theres a few of them but im sure I could find it.

It describes there how to use arrays instead of globals, because there are no globals.

So that doesn't help him. I think however it might be the only way.

In DBC you should be using subroutines where you can, instead of functions.

That will get around the global variable problem, but with the Search and Replace feature in the IDE, you could fairly quickly replace the variables names.

Just replace all occurences of 'VariableName' with VariableName(0) then add a DIM VariableName(0) at the start of the program. Just repeat with all the vars you need to be global.

As you have functions in DBC, there's no obvious reason to change all the functions to subroutines as many should work just fine.

This might actually be a bit quicker than converting all the functions to procedures...

Unless you don't want to be doing a hack, which I think using single item arrays is. In BASIC it's always been proper to use subroutines when you want to share the use of variables in multiple procedures and the main loop itself. The only reason most of us use mainly functions in DBP for main procedures now is because we have the global keyword.

@TDK: Yeah, I did that.
Unfortunately, it fell when it occurres to me that DBC doesn't support alpha blending on sprites; I managed to convince the staff to temporarily install DX9.0c for my presentation though

Rudolpho, just do a google search for "Alienware Dark Basic Trial". The trial version released for the alienware competition still has a download page on TGC's site. IIRC the DX version is 7, so it might run.
