Forums Scripts & Popups /continue with timer, or goto with timer

hey,

i'm writing a script which reads a logfile, i want that if my while loop doesnt matches that it executes the while loop until it matches or i end the loop, but as you all know, only /continue would cause a crash because of the count how much times it gets executet in a second, so thats why i want/need to use a timer function or something similar where i can specify a delay time to execute this /continue command. If someone of you all has another idea how i can manage stuff like that please tell me. i'm happy about it then.
my while loop looks similar to that:

while (%MyVar == $false) {
echo blabla
/timer 1 15 /continue
}
else /break

thanks.
