GEOSoft Posted December 22, 2003 Share Posted December 22, 2003 I have a whole section of a script that I want to use as a function so I can recall it later is need be. When I want to read a variable that is created inside of the function how do I read it from outside. Here is an example; Func 1() $Var = "Path" EndFunc MsgBox (0,"",$Var) Exit That will not work, it reports an undeclared variable when it gets to the $var in the MsgBox. However if I don't use the function everything is fine, for example $Var = "Path" MsgBox (0,"",$Var) Exit There must be a trick to it. :-( George Question about decompiling code?

Valik Posted December 22, 2003 Share Posted December 22, 2003 (edited) You have to make the variable global in one of two ways. You can either declare it outside any function as follows:$Var = 0Or you can use the Global keyword to force it to global scope:Func 1() GLOBAL $Var ; When using GLOBAL $var = "Path" I got a subscript error $Var = "Path" EndFunc 1() MsgBox (0,"",$Var) ExitEDIT: One other thing I forgot to mention, you have to call the function before the variable will be initialized. I've fixed the code in the example to do this. (It's probably safter to just use $var = 0 outside any function for a global variable...)

GEOSoft Posted December 22, 2003 Author Share Posted December 22, 2003 Thanks Valik. I managed to work it out from there. And path was not the actual value I was working with, I used it only for the example. The actual strings were registry calls at the beginning of the script and further down I had to go back and refresh the strings. That is when the GoSub\Return routine would have still come in handy.
