I have a problem that I can't quite figure out, and I'm not sure if it is possible.
What I have is two sets of data with a matching key. I want a sort/merge that eliminates records from file 1 if the key is found in file two
ie
F1
AAAAA
BBBBBB
BBBBBB
CCCCC
DDDDD
F2
BBBBBB
CCCCC
Output
AAAAA
DDDDD
Does anyone have any idea if this is possible or where to begin on accomplishing this? I have been searching online and through the reference guide but I can't seem to find anything.
