is there a way to change the flow of a script

i have the following code.

; script selectforaddp2

hotkeyset("^ab", "pauseit")

while 1




$sencmd = '"p:\mchprocess\selectformcheditB.exe"'
	   $retcode = runwait($sencmd)
			  if $retcode = 8 Then
	  msgbox(0,"","User " & $personid & " not for processing")
	  ContinueLoop
	 endif
	 if $retcode = 7 Then
	 ; msgbox(0,"","User " & $personid & " not for processing")
	  ContinueLoop
	  endif
 
	sleep(600)
   
while 1
$PID = ProcessExists("mchupdauto.exe") ; hold till mchupdauto start executing
If $PID Then
 exitloop
EndIf
sleep(2000)
wend

func pauseit()
 msgbox(0,"","Select for Add is paused")
endfunc

wend

selectformcheditB.exe sets off a series of other scripts where mchupdauto is the last one execute.
this script sets the while loop waiting for that event.
many times things go wrong before mchupdauto gets executed
i can use the hotkey to send it the pauseit function.

is there a way in the pauseit function or an external script to direct this script (selectforaddp2)
to return to the begining of its while loop and hence execute selectformcheditB.exe?
