You may want to check out Mec TechNote #158 (released in the September batch)
called "Frequently asked MultiFinder Questions". In it, Jim Friedlander
answers the questions "How can I tell if WaitNextEvent is implemented?", "How
can I tell if the MultiFinder temporary Memory Allocation calls are implemented?", "How can I tell if my program is running in the background?", "When does
juggling (context switching) take place?", "Can I disable SUSPEND/RESUME
events?", etc. 

It also makes a reference to the "MultiFinder Developer's Package" presumably
available from Mac DTS and soon from APDA.

I'd suggest maybe writing a simple XCMD to do those things for you. As for
testing to see if a string is numeric, try the "value" function (Syntax:
"the value of <source>", or "value(<source>)"). This function evaluates the 
string in <source>. However, I don't know how it chokes if you set <source> to 
"MarseyDotes" or something like that.

Keep those HyperCard suggestions coming; I noticed that Dan Winkler subscribes
to this group.
