I have a function which is sitting in a file called resourceHandler.agc and is included by main.agc.

When I run this code during the main loop, unless I put a print("") command in it, the screen goes blank and I am assuming it never returns from that function. This was the main reason for putting a print command in there, but without it, it never returns. Anyone else encountered this? The code works fine once the print command is present.

Why do you have both a "return" (from gosub) and an "endfunction" call?

I used to hate the thought of governments having orbital mind control satellites,
but now I can't really seem to care.

Oh that shouldn't be in there. It was put in when I was trying to get it to come back. I found I couldn't gosub processUpKeep( something ) as it spits the error "Parameter mismatch in expression 'processUpKeep'. So I just called the function by typing processUpKeep( something ). When it first showed the black screen problem, is when I put the return in - assuming calling a function without gosub would need it.
I just took out the return then anyway and it still has the problem that if I take out the print command it never returns from that function.

Is it because I'm doing all this stuff in an included file? Do most people just use 1 file for everything? I'm getting some other weird errors which might come from this method of using included files.

I can only confirm that it's not due to using included files. I have all my functions in several included files in all my projects

I'm just wondering why I'm getting all these weird errors and no one else is? Like making a function work by putting a print command in, or leaving a print command out to make another piece of code not crash.

I have windows 7 running on. 64 bit machine using agk 1075.

I'm seriously thinking of ditching it because I waste so much time with these silly errors.

Have you tried upgrading to 1076? It might make a difference, it might not.

If the project isn't too large, I'd be happy to take a look at it.

Firstly, have you now removed the remnants of the gosub method? They may be interfering, and causing memory location issues.

If it still doesn't work, create yourself a debug file. At the very simplest level, open the file at the beginning of your program, and close it at the end. In between, write lines out to it to establish where you got to, and the state of any important parameters.

Longer term, make yourself a set of debug functions to manage debugging output to a file. It may take a couple of hours now, but save so much more time later.

Yes the gosub functionality has been removed. I'll try the debug function as you've mentioned.

This is resolved as mentioned in this thread. I was trying to mix gosubs and function calls. You can't.
