@devilspride, welcome to the AutoIt forum.
notice that when you #include some external file, that file which you create yourself (often known as UDF) does not have to include functions only - it can include whatever code you choose, be it variables or constants declarations, option statements, function calls, etc. so you can put all the region of the COMMON INITIAL VARIABLES into a dedicated file, and #include it in all your scripts.
or am i missing something?
