the other thing i cannot figure out is how to i execute funtion once and then reset loop counter after it reached = 21 and begin counting from 0

global $i = True
$example = true
Global $loop = 0

func 1

 If $loop = 21 Then call("func4")

func 2

example

func 3

 

$loop = $loop + 1
            ConsoleWrite($loop&@CRLF)

func4

action

loop reset

call(func1)
