Hi Rob,

Klaus already mentioned the 'launch' and 'open
process' commands ; in addition, you can also run the
executable using the 'shell' function.
This way, if the target app is a command-line tool,
you can read back the result of calling the executable
as written to 'stdout'.
Please note that using the 'shell' function will block
your application until the .exe has finished running.

Hope this helped,

Jan Schenkel.
