Global arrays

[Psycho]

Can arrays be globally defined? If so, is there a special way?

I am trying to use a subroutine to load equipment names from a text file, then display them in a listbox. After pulling the names from the textfile, I am loading them into an array named "equipment$(a)". I have defined equipment$ as global but if I don't include the listbox command within the subroutine, it shows up completely blank. Stabbing in the dark, I tried defining equipment$() as global but that gives me an error. Obviously, using a gosub instead of a sub eliminates the problem as well but I'd like to know if and how you can globally define an array like this.

Any advice would be appreciated.

You can not use the GLOBAL command for arrays.
To define a global array, you DIM it in the main part at the very top of your program.

dim GlobalArray(100)

'some code ...

sub ...
    dim LocalArray(100)

    'some code ...
end sub

Thank you Stefan.

What worked fine for me was to declare the array name in the global statement, and then define it in a dim statement, as:

global arrayname
dim arrayname(10)

If I didn't use the global statement, using the arrayname in a subroutine got me a new, empty version.

The variable used with the GLOBAL statement in the above example is a simple global numerical variable.
The array used with DIM is a global array, if it is first dimmed in the main portion of the program.
