alternative to execute [message #47205]

I'm trying to think up a good way to implement a user-defined function
which would run in the IDL VM. The function might involve any of about
300 similar 2-d arrays, each of which is quite expensive to generate.
So I thought to obtain the function as a string, scan it to see which
arrays are needed, generate them, and then apply the function with
'execute'. But 'execute' is excluded from the VM.

A typical function might look like:

result = b123 / b100 - .9 * b050 / b035

Without execute, I can only think to attempt to write some kind of
arithmetic interpreter. Would anyone have a suggestion for a way to get
IDL to do this more directly?
