>First, thank you very much for you suggestion. But, again, I probably didn't say the initial question correctly. The m.lcInput can have more than just this '!empty(.. " but other expressions. Let me give you a good example:
m.lcInput = "Mytable.FieldXyx = '233' and (MyTable.Field233 > 344) and !empty(mytable.myfield) and someothertable.field3 = '333'"
As you can see that the expression "!empty(mytable.myfield)" could be somewhere in the middle, beginning, or end of the entire string.
