Local vars

[inlander 0]

When using the Local keyword on a variable within a function, such as in the example:

 

Func Example()
    ; Retrieve the data stored in the clipboard.
    Local $sData = ClipGet()
...

 

EndFunc   ;==>Example

 

is this local to the function, or local to the script?  If local to the function, how would I declare it local to the script?

(I want to check it outside the function.)   Can a function return a value, as in most other languages?

 

Also, I am not used to on-the-fly declarations with an assignment.  How is a variable explicitly declared?

 

TIA for your help.

Use keyword Return in the function to return a result. Variables decleared inside the function with Local will only exist inside the function.

could be.

1

global $data=""

 

func getdata()

$data=clipget

endfunc

2

local $data=getdata()

func getdata()

return=clipget()

endfunc

3

also could use byref.
