Using a formula in a field in RPG

["Charles Abbott" <cabbott@xxxxxxxxxxxxxxxxxx>]

We are trying to mimic some old PL/1 code that uses formulas stored in a
file and are executed at run time.  We are trying to figure out how we can
execute the "value" of a formula field as an operation in RPG (assume V5).
The formula will have valid field names from the program and normalized
operation codes.  Something like "(width * length)/12" would be stored in a
field in the file and executed at run time as part of the code.  Any ideas?

Thanks,
