You could put the account number in an array and check if it exists in the
array with a %lookup or build the subfile with SQL and and use the distinct
clause when selecting the records.

I have a subfile that is used for data entry. One of the columns in the
subfile is an account number. An account number can only appear in the
subfile once (i.e. Unique key). Does anyone know how to check for that,
other than writing the subfile to a temporary uniquely keyed disk file, and
monitoring for a duplicate key error?

Thank you,

Doug
