Func... And Return

[Guest Monkey]

Hello everybody...

This is my first post, so be kind...

Global $x
x(1,2)

func x ($a,$b)
$c=$a+$b
If $c=5 then
;c=5
    Return ("1")
    msgbox (0,"","C=5")
Else
;c<>5   
    Return ("0")
    msgbox (0,"","C<>5")
EndIf
EndFunc

I don't really understand the 'Return' issue. Since the msgboxs are not displayed, where the script "goes" once it arrives to the Return command?

Thanks for the help!

Return exits the function. The program starts again from the line after where the function has been called.

you can assign the func value to a variable and use it, the variable will have the return value.

E.g.

Global $x
$h = x(1,2)

If $h = 0 Then MsgBox(0,"","the function returned 0")
If $h = 1 Then MsgBox(0,"","the function returned 1")

func x ($a,$b)
$c=$a+$b
If $c=5 then
;c=5
Return ("1")
msgbox (0,"","C=5")
Else
;c<>5 
Return ("0")
msgbox (0,"","C<>5")
EndIf
EndFunc

Return basically means: Stop the function here and return to where it was called from ... optionally with a return value...

Global $x
$rc=x(1,2)
if $rc = 1 then 
  ; c = 5
endif

func x ($a,$b)
   $c=$a+$b
   If $c=5 then
     ;c=5
      msgbox (0,"","C=5")
      Return (1) 
   Else
     ;c<>5 
      msgbox (0,"","C<>5")
      Return (0) 
   EndIf
EndFunc
