time events? [message #16750]

I'm using IDL widgets to launch other applications on a unix network of
boxes using the SPAWN command.

It would be nice to generate events automatically at certain times of the
day. Alternatively, if the contents of a pipe could generate an event, that
would work too. What I don't want to do is hard code a loop that
continually reads a file or pipe, or checks the system time, and prevents
the user from using other functions.

Specifically, I need a way to determine whether a SPAWNed job is done so I
can have IDL launch another one automatically.

Thanks. Chip
