I have a dba file in my project that contains a function that creates all my global variables. I call this function at the start of my program, and my variables are all available to me with the right values.

However, when I create a type in my globals file, it doesn't seem to work as I expect. I get the error: cannot find field 'x'

code from globals.dba


code from main.dba


If I move all of the type declaration stuff into main.dba it works as expected, but obviously my code becomes a right mess. If I can move this kind of thing out to a seperate source file, it'd make my life easier.

So is there a way to get types working globally?

[edit -> just noticed a typo in the code, but it doesn't affect the problem

That's what I do.

There's the globals.dba file, and a funciton in there called init_globals() where I setup my variables.

I call that function in my program before I try to use any of my variables.

All the variables declared in that function work perfectly except for the type declaration.

Not true. I always put my types at the end of my dba files.

Zotoaster: Maybe when my posts have been authorised by the mods and this thread makes more sense again () you wouldn't mind maybe pointing out where I've gone wrong?

Thanks.

The Type declaration is inside the init_globals() function in globals.dba and that function is called immediately after doing stuff like setting the screen res, so well before I get into actually doing anything with my program.

Maybe I need to restructure, but I'm just a bit worried that the compiler is going to be super picky about this stuff and I'll spend ages reorganising my code, and still not be any further forward.

It's not the end of the world to have the type declarations in my main dba file, so I'll probably just live with it until I better understand what's going on.

Well, I have all my declarations embeded in a subroutine that's called after setting up some constants.
I have several function declarations before my type-including routine, which is actually in my third included source file, and everything works just fine.
Try changing your function to a routine if you don't want to put it at the beginning of your main source (change the function init_globals() line to init_globals: and the endfunction line to return. Then call this using goSub init_globals).

I usually have all my Global, Types, and Array declarations in my Main source file. Then I set Function Main() at the end. The rest of my source files just hold all the different functions for the game.

Subroutines can also be called in #included files, as well as the main source file.
