Segment spin data set specification - Key = '8014'
DALSEGM specifies the number of logical, line-mode pages (the segment) to be produced for a SYSOUT data set before the segment becomes eligible for immediate printing.
When you code DALSEGM, # must be 1 and LEN must be 4; PARM must contain a positive hexadecimal integer from X'00000001' to X'0001869F' (equivalent decimal value from 1 to 99,999).
Example: To specify a segment of 100 pages, code:
KEY # LEN PARM
8014 0001 0004 00000064
