EOF vs. LIMIT
Under MPE/iX it is very common to have a LIMIT of 4 million and an EOF of 400. This is because the large LIMIT does not impose a large extent size on the MPE/iX file, due to the unlimited number of extents. When Qedit Texts a file, it remembers the number of records beyond the EOF and adds that count to the size of the file on a later Keep. Qedit now restricts that extension beyond the EOF to 100,000 records.
