1. How, using I4GL, do you evaluate a numerical expression held in a CHAR variable

Does anybody remember the 'EVAL' command in Basic?  It allows you to
compose a
string variable, e.g. A$="((127-82)/42)*27.5" and then assign the value of
the string into
a numeric variable, i.e. A=EVAL(A$).

Currently I am using a SQL query to do this calculation for me and it is
proving inefficient.
I'm sure there is a 'text box' answer for this solution, something along
the lines of calling a function
with a pre-constructed string, and for it to return the evaluated answer
with a level of decimal
precision.

Any ideas would be gratefully appreciated.
