How do i define the layers$[] array so this will work. I don't want to have to make it global (when i make it global it sees the array)

If you scroll near the bottom there are a couple sections on using arrays in functions, hopefully this will help, cheers.

you can use the keyword LOCAL but I don't know if this will solve the problem.
You also have 3 lines that don't even print the element number. Have you used layer$ anywhere else in your program?

The help files say that arrays in V2 are backwardly compatible. That means they will always be global.

Nice one dude, no worries. I gathered you didn't mean it maliciously in any case, but reading it back it does sound a bit demanding haha.

You can have local arrays, but for some reason you can't assign values to them on the same line they are defined like you can with global arrays. (Possibly a bug)

Your code is defining a local array, but failing to set any values to it because of this. If you set a value in the array on a separate line it's value will show.

eg:

function test_function()
layers$ as string[4] = [ "o", "b", "r", "s", "h" ]
layers$[1] = "B"
layer as integer

for layer=0 to layers$.length
print(str(layer)+"."+layers$[layer])
next
endfunction
