SPACE=({CYL | TRK | KIL | MEG},({primary},{secondary},{directory}),{RLSE})

Default	None
Allowable Values	See the following explanation of this parameter.
Minimum	Not Applicable
Maximum	Not Applicable

This parameter defines the values used when creating a new file on a z/OS system. The values can also be specified in the ALLOC_TYPE, ALLOC_PRI, ALLOC_SEC, and ALLOC_DIR parameters. If both parameters are specified, the last parameter specified takes precedence.

The SPACE parameter format is similar to (although not as flexible as) the z/OS JCL SPACE parameter. The values specified as PRI, SEC, and DIR are the primary, secondary and directory block allocation. If RLSE is specified, space will be released after the transfer is completed. If RLSE is not specified, space will not be released after the transfer is completed.

If the SPACE parameter is not defined, the allocation parameters associated with the input file is used for the output file. CYL indicates that allocation is done in Cylinders. TRK indicates that allocation is done in tracks. KIL indicates that allocation is done in Kilobytes (thousand bytes), while MEG indicates that allocation is done in Megabytes (million bytes).
