Write EOF Record (option 5.5)
Use this option to write a logical EOF marker into a sequential disk file.
File Manager retrieves the record at the specified location and rewrites it as an end-of-file indicator. File Manager writes a special record with a data length of zero (null record). All data on the track past this EOF record is lost. File Manager prints a log of the retrieved record, provided your print output is not routed to the terminal. Alter the destination of the print log by changing the value in the PRINTOUT entry field of the Set Print Processing Options panel (see Set Print Processing Options panel (option 0.1)). The EOF record has a data length of zero.
