Richard, it might help with cpu efficiency to use a different wait in
the loop, polling every second, let's say:
repeat
add 1 to count
if there is a file xxx then exit repeat
wait 1 second -- I'm assuming that this form of wait just idles the
engine
if count >= 18 then exit repeat -- ie.there's a problem
end repeat
Best,
Mark

I have a script that gets to a point in its processing where it
needs to wait up to 18 seconds for the appearance of a file. I know
I can use a simple "repeat until there is a file xxx" type of loop
(exiting from the loop if the time exceeds 18 seconds), but I'm
thinking there's a better way to handle this. This script is
running on a cgi server and there could be numerous simultaneous
scripts doing the same thing... so I want to minimize the load on
the CPU.
Suggestions?
Thanks.
