Services and Utilities for UNIX Files

The following services and utilities support UNIX files:

• Access method services (IDCAMS) REPRO—REPRO by DD name is supported and uses QSAM.
• IDCAMS PRINT—PRINT by DD name is supported and uses QSAM. Instead of displaying 'RBA OF RECORD', PRINT displays 'RECORD NUMBER'.
• DEVTYPE macro—DEVTYPE provides information related to the UNIX file. If PATH is specified in the DD statement, DEVTYPE returns a return code of 0, a UCBTYP simulated value of X'00000103', and a maximum block size of 32␠760.

The following services and utilities do not support UNIX files. Unless stated otherwise, these services and utilities return an error or unpredictable value when issued for a UNIX file:

• IDCAMS—ALTER, DEFINE, DELETE, DIAGNOSE, EXAMINE, EXPORT, IMPORT, LISTCAT, and VERIFY
• OBTAIN, SCRATCH, RENAME, TRKCALC, and PARTREL macros

  These macros require a DSCB or UCB. z/OS UNIX files do not have DSCBs or valid UCBs.
