Big problem with var

[NguyenLeNhatTan]

I have a script like:

dim $myVar

$myVar=22

MsgBox (4069,"Title",$myVar,10) --> out Msgbox is 22

ChangeValue($myVar)

MsgBox (4069,"Title",$myVar,10) --> out Msgbox is 22 too

Func ChangeValue($inputVar)

$inputVar=100

EndFunc

How can I change in my Func "ChangeValue" to change $myVar to 100 (not use return in "ChangeValue")

Please help me, thanks so much
