One more note on my previous reply:
The only real example that I have ever used this technique was when I had a very peculiar data set handed to me:

VAR1  OP  VAR2
1     <   2
23   <=  .666
45    /   234

..

I needed to find the answer to the operations described in each row of my data set.  Instead of trying to code a select statement for every possible operator, I used the resolve and sysevalf functions.  They were slow, but I didn't have THAT much data.

answer=resolve('%sysevalf('||compress(var1)||trim(op)||compress(var2)||')');

It works like a charm and is a very interesting application of the resolve function.
