Sorry, that was just a typo. Even so, what you're suggesting doesn't solve the problem.

---------- Post updated at 05:18 AM ---------- Previous update was at 05:11 AM ----------

I'm not breaking the loop. My script is reading the GPS speed every 30s and if the speed is less than 10, i want whatever is within the subroutine (function) to stop. Once the speed exceeds 10, it will get going again. The problem is that the variable "pause" isn't being updated within the subroutine.#

I should add that I don't want to put the test itself within the function. I've simplified the code above on purpose and there's an additional component within the for loop that counts the number of times the speed is less than 10. So, the structure must remain intact.

TTYPLAY(1)						      General Commands Manual							TTYPLAY(1)

NAME
ttyplay - player of the tty session recorded by ttyrec SYNOPSIS
ttyplay [-s SPEED] [-n] [-p] file DESCRIPTION
Ttyplay plays the tty session in file, which was recorded previously by ttyrec(1). When -p option is given, ttyplay output the file as it grows. It means that you can see the "live" shell session running by another user. If you hit any key during playback, it will go right to the next character typed. This is handy when examining sessions where a user spends a lot of time at a prompt. Additionally, there are some special keys defined: + or f double the speed of playback. - or s halve the speed of playback. 0 set playback speed to 0, pausing playback. 1 set playback to speed 1.0 again. OPTIONS
-s SPEED multiple the playing speed by SPEED (default is 1). -n no wait mode. Ignore the timing information in file. -p peek another person's tty session. SEE ALSO
script(1), ttyrec(1), ttytime(1) TTYPLAY(1)
