Multi-Dataset Processing Examples Processing Tape Datasets
7-22 User Reference
In the example above, the options used in the creation step are:
Option Action
DSN='xxxx(+0)' The "+0" in parentheses indicates that this is a generation dataset
(see the DDGEN configuration option in the BIM-EPIC
Installation and System Guide).
OPTION=(SYS010) Inhibits LUB allocation for this dataset. This is equivalent to
TLBL option code 64. In addition, this forces the use of SYS010
(which has no TLBL equivalent).
UNIT=TAPE Tells BIM-EPIC to create a tape label. This would be determined
in standard VSE JCL by using a TLBL.
FREE=END Holds the assignment at close for all but the last dataset processed.
This is equivalent to TLBL option code 8.
DISP=(NEW,KEEP) The NEW subparameter indicates that this dataset version will be
created as output. The KEEP subparameter causes the tape to be
unloaded at close unless VOL=(,RETAIN).
VOL=(,RETAIN) Inhibits rewinding the tape at close (overrides the DISP
subparameter KEEP). This is equivalent to TLBL option code 3.
VOL=(PRIVATE) Causes the tape to be unloaded at close. This is equivalent to
TLBL option code 2.
The option used in the read step are:
Option Action
DSN='xxxx(0)' The zero (0) in parentheses indicates that the current version
(version 1) is to be processed.
DISP=(OLD,PASS) The OLD subparameter indicates that this dataset version already
exists and will be read as input. The PASS subparameter indicates
that this tape is used later in the step or in a subsequent step.
