Thank you for your input Paul.
My largest table is 30 fields with 50,000 records.
The calcs are not terribly complex; most often they take 3 to 4 values from several tables and perform a common operation on them. One complication is the necessity to do some Immediate IF (IIF) tests within calculations to determine which multiplier to use in given calculation.

The note on C as a compiled language is a good one. It makes sense not to expect as much from the interpreted language. I wonder how they would compare in a head to head test on my calcs.
