#include ? [Solved]

[JohnOne]

Never written a script large enough where I though I migh need them, but decided to try anyway.

But it appers I dont understand them enough.

Main script

#include 'MyInclude.au3'

Global $var = "variable"

_MsgBox()

Include

Func _MsgBox()
MsgBox(0,"",$var)
EndFunc

It turns out A global var from main script does not carry across includes, which is the opposite of what I thought.

I know I can put everything in one .au3, but Im just curious as to the reason I get warnings about undeclared variables.

If anyone has the time to explain I'd appreciate it.

Well I'd say luckily declaring Global variables in one script does not in any way affect the included scripts' variables. I woulnd't really like that. If you want to pass variables around, do so in a function call. For example, you could have passed it as an argument if you built a function _MsgBox($var)

Apparently it does work if you include it after declaration (@Yashied) .. ah well, I always start with includes anyway so it luckily will not affect me
