Don't listen to all the nonsense. Common blocks are fine.
RSI uses them all the time in the IDL code they write. :-)

Is your initialization routine a procedure, or is it a
main-level program. You won't be able to have any
main-level programs in a run-time environment. If it
is a procedure, I can't see why this won't work as
a run-time program. Your "main" routine calls
the initialization routine, then fires off the
tools, right?

Cheers,
