RE: Subfile size equals page size. SFLEND(*MORE) and eof

["Booth Martin" <booth@xxxxxxxxxxxx>]

welll....  I thought of that but this program allows the user to select
records, so all records will rarely be eligible.  Testing the whole file is
not practical.

And yes, there are thousands of records in the real file.

How about determining the number of records in the file, and if it's an
even multiple of the SFLSIZ, turn on SFLEND (which is also conditioned
by eof) when you read the last record.
