Thanks alot everyone,
Actually, I just start learning about Programming language. So, each your
solution is a good suggestion for me to learning. Thanks so much.
Please help me one User-defined Functions to solves this when my data like
this:
EA;BX;CA
CA;EA
BX;EA
And when run UDFs, output is:
CA;BX;EA
EA;CA
EA;BX

One again, thanks so much
