FUP Commands

All partitions of a file are created with the same format version. For files that are
not key-sequenced, a partition created independently must have the same format
as all other partitions of the file.
Caution. If you use the ALTER command to change a partition to a different format from the
rest of the partitions, the file system reports errors. FUP does not check for such errors.

ALTER command with filename as primary partition of an enhanced key-
sequenced file used with alter-option MAX EXTENT and PARTONLY option is
executed, but the maximum extents of the primary partition do not change.

ALTER Examples

-ALTER MYFILE1, CODE 10


To assign the alternate-key file MYFILE4 to MYFILE3 and give it key-file number
