Access Method | Description | Reference |
---|---|---|
BSAM, QSAM | The application program sees the UNIX file as a single-volume, sequential data set that resides on DASD. | See Writing a UNIX File with BSAM or QSAM. |
VSAM | Accesses a UNIX file as if it were an entry-sequenced data set (ESDS). UNIX files are the only type of data sets that you can access with both VSAM and non-VSAM interfaces. | See Simulated VSAM Access to UNIX files. |
BPAM | Provides read-only access to UNIX
files. BPAM treats a UNIX directory as a PDS or PDSE directory, and
treats a UNIX file as a PDS or PDSE member. BPAM ignores any subdirectories
in the directory that you specify. Restriction: You cannot use BPAM to write to a UNIX file. |
