I'd say that particular case is handled just like any other case. The input variable/symbol is a completely separate entity from output string "VARxxxxxx" you replace it with, except for the 1:1 mapping of input vs. output strings. Examples: INPUT OUTPUT abc VAR000001 Color_Value VAR000002 VAR000001 VAR000003 VAR000004 VAR000004 X_Prime VAR000005 Nah...that was too easy. I musta missed something... -- Frank Manning
