SPACE Parameter
Description Use the SPACE parameter to specify the disk dataset allocation. In
addition, use SPACE to:
Specify allocation size
Permit or inhibit truncation at close for an output dataset
Invoke dataset fragmentation if contiguous space is unavailable
Align allocation on track or cylinder boundaries on CKD devices
Use parentheses to enclose the SPACE positional subparameters.
Additional parentheses are used to enclose the actual allocation amounts
when supplying a prime allocation size with a secondary size and/or an
index size. SPACE has two syntax types of syntax, one for
BIM-EPIC-controlled datasets and one for uncontrolled datasets.
Note:Note:
The UNCDSK configuration option allows use of DD statements for
uncontrolled disk datasets.
