Start Track 1 Datasets
Description To define a Start Track 1 dataset, you must specify allocation information
with an EXTENT statement.
DLBL
Statements
The EXTENT statement for a Start Track 1 dataset differs slightly from
the standard VSE EXTENT statement. To use a Start Track 1 EXTENT,
do the following:
Specify a BIM-EPIC disk pool instead of a volume serial number
Specify a relative starting track/block of 1
Example A Start Track 1 dataset is allocated in POOL01 with 20 tracks.
// EXTENT SYS003,POOL01,1,0,1,20
If you specify a Start Track 1 EXTENT for a controlled dataset,
BIM-EPIC ignores the EXTENT information. Start Track 1 allocations
can also be specified in DD statements.
