Hello,
I appear to be stuck again with another simple problem. This time I have defined a function in a library file and called it from my program.
The interpreter is returning an error "No such variable in module".
I believe it has something to do with the LOCAL variable I am using but I cannot seem to figure it out after reading the tutorial and documentation on procedures and functions.
Code:
DEF FN_get_window_title
LOCAL title%
DIM title% LOCAL 1000
SYS "GetWindowText", @hwnd, title%, 1000
= $$title%
PRINT FN_get_window_title
What am I doing wrong?
Thank you.
