The last dataset does not require the tape and drive to be held, nor does it
require a dataset drop.
Example 3 The following example creates multiple datasets with different DTF
names. Because different DTFs use different logical units, a logical unit
must be supplied in the dataset definitions.
// JOB XYZ
*
*
----------------------------------------------------------+
* CATALOG A PRIME AND 2 SUB DSN'S +
*
----------------------------------------------------------+
*
// EXEC TSIDMNT
CAT 'PRIME' SYS010
CAT 'SUB1' NSU='PRIME' SYS010
CAT 'SUB2' NSU='PRIME' SYS010
/*
*
*
----------------------------------------------------------+
* CREATE A PRIME AND 2 SUB DSN'S. PROGX PERFORMS 3 OPENS, +
* ONE EACH FOR TAPE1, TAPE2 AND TAPE3. +
*
----------------------------------------------------------+
*
// TLBL TAPE1,'PRIME',,,,,,11 8 + 3
// TLBL TAPE2,'SUB1',,,,,,11 8 + 3
// TLBL TAPE3,'SUB2',,,,,,2 2
// EXEC PROGX

The following describes the options used in the example above.
Because LUB allocation is inhibited through the dataset definition, 64
does not need to be specified on the TLBL.
Note:Note:
LUB allocation is inhibited as the result of SYS010 being specified in the
prime dataset definitions and the subdataset definitions.
Example 4 The following example is similar to Example 2. Although, it may seem
more complicated, the BIM-EPIC DD facility offers greater flexibility
than TLBLs.
Code Action
2 Dismounts the tape (for the last dataset)
3 Inhibits rewind at close (for all but the last dataset)
8 Holds the drive assignment at close (for all but the last dataset)
