Subject: Verifying a one-to-one relationship between two fields
I have a non-keyed PF, with some 44k records. There are two fields,
CUSKEY and CUSCOD, neither of which is a unique key to the file. I
suspect that there is a one-to-one relationship. Can somebody suggest
the easiest possible way to verify this?
