We have a frequently used function for translating uppercase to lowercase. The Cobol code we use is:
INSPECT TEST-DATA3CONVERTING 'ABCDEFGHIJKLMNOPQRSTUVWXY |

powerhawk,
Add the following statement before the ID division
The above parameter will produce a listing of the assembler-language expansion of your source code. Now take a look at the compiler listing after successful compilation. The process which generates least instructions will be the optimal one
Hope this helps...
Cheers

Powerhawk, I have used the same technique that you used after testing. Notice that if you use literal strings in you INSPECT statement it will generate inline code. If you use variable names then it will generate a call to a library routine. Even though the call to the library routine generates less ASSEMBLER code it is not as efficient as the inline code.
Try it and see... I did and that's what I found.

You can use the intrinsic function "LOWER-CASE".
