Compare Units From Different Sources

[theamandagail]

Hello,

I have file with a set of Units. I want to compare the same file we've used in the past to ensure we are maintaining the same units.

I have tried the "join" option but not sure that's helped me decipher which units have not made it into the current unit file.

For more clarifications:

Current unit file: Unit 1, 2, 3,4

Historical Unit File: Unit 1,2,3,4,5

What routine can I build to show that 5 cannot be found in the current file?

Thanks a lot!
