── CRUNCH ── ( ──<file identifier>── ) ────────────────────────────────┤
Explanation
The CRUNCH statement closes and crunches a file. Crunching causes the unused portion of the last row (beyond the end-of-file indicator) of disk space to be returned to the system. The file to be crunched must be a disk file. Once a file has been crunched, the file is released and can no longer be expanded.
Examples
The following are examples of the CRUNCH statement:
CRUNCH (LONGFILE)
CRUNCH (BITSFILE)
