Polling in Rev (send verses wait)

[Glen Bojsza]

I am working on an app that needs to do a polling routine every N
seconds (where N is defaulted to 10 unless the user defines it
themselves). The routine gathers information from some files and
parses it with the results being displayed in the appropriate fields.

This routine needs to be a run as a background process because the
user will be working with the application to update information etc.

The Rev docs lead me to think that either the send or the wait command
could be used. I was hoping someone would shed some light on which
selection should be used in this case.

thanks,
