MOM script for Citrix idle sessions: ? about running shell commands

At the end of this message I've pasted a script we're trying to modify
slightly. I don't believe it is VBscript or javascript but these are
the closest groups I could find with my limited programming knowledge.
Basically, we are trying to add a few lines to this script that will
execute a few shell commands (see comments at the very end of the
code). We think this may be ActionScript2 but aren't sure.

If you can offer any help, or know of a more approrpriate place for me
to post this message, please let me know. Thanks!
