Match values between two tables

[#1]

Hi all.

I have two data sets, each with a list of users.

The first data file is loaded in, and has like 100 users.

The second is loaded in, and has 50 users.

If a user is on both sets, I want to create a new field called UserType and call those users 'B'. If they are only on the original list, then 'A'.

Any ideas?

I've done some research and am thinking to use the exists() command but am not sure how to implement this fully.

Thanks
