is there a way to pass an array as a perameter to a function? It would be really great if someone would tell me how... thanks a lot.

Well that depends on what u want to do. You could do something like this:

Dim var(3)


For t = 1 To 3
	value = 5
	var(t) = AssignVariable(variable,value)
Next 

For n = 1 To 3 
	Print var(n)
Next

WaitKey()

Function AssignVariable(variable,value)
	variable = value
	Return variable
End Function

And that would assign the variable using a function.

You don't need to pass arrays to functions. Arrays are always global so you can access them from within functions anyway.

Oh yeah. I forgot about the global part and I thought that you didnt need to pass them to functions but i didnt want to burst anyones bubble

This has been covered a million times before, but..

You can pass 'blitz' arrays to functions, like this:

Local a[20]

blah a
Print a[10]
End

Function blah(b[20])
	b[10] = 501
End Function

Note that they are single dimensional and cannot be resized, but you can store them in Type objects:

Type thing
Field a[20]
End Type
