Forums Scripts & Popups $remtok problem

Hello there.
Can anyone say me is there a way delete ALL the tokens with the $remtok? I have tried to use zero (0) as N, so it looked like this:
$remtok(%teststring,a,0,32)
but it didnt worked for me...

while (%teststring != $remtok(%teststring,a,1,32)) { var %teststring = $v2 }

this removes them all

Thank you! That works just fine
