Simple func not working any more


Recommended Posts

byref means that the value is returned to the variable in the calling code eg:

$a=5
test($a)
msgbox(0,"test", "$a=" & $a); $a will still be 5

Func test($a)
   $a = $a * 10
EndFunc
$a=5
test($a)
msgbox(0,"test", "$a=" & $a); $a will be the retruned result thus 50

Func test(byref $a)
   $a = $a * 10
EndFunc

If you don't want to change the value of $a you can use the return option

$a=5
$b=test($a)
msgbox(0,"$a=" & $a, "$b=" & $b); $a stays 5, $b will be the returned result thus 50

Func test($a)
  $a = $a * 10
Return $a
EndFunc
