6			Schedule Request control
	0	SCDTIME	Initiation delay specification B'0' Interval B'1' Time Not supported by IMS
	1-7		Reserved
7-m		SCDDPN³	Name of process to be initiated. (Required field)
m+1-n		SCDPRN³	Name of the primary resource for the process to be initiated
n+1-p		SCDRDPN³	Suggested name of the return process
p+1-q		SCDRPRN³	Suggested name of the primary resource for return process name
q+1-r		SCDDQN³	Name of queue associated with process
r+1-s		SCDREQN	Name of this process request instance (Not supported by IMS)
s+1-t		SCDDELY	Time interval to be decremented prior to initiation of destination process. (Not supported by IMS)

Notes:

Must be 0 on both input and output.
On input, this field is ignored. On output, this field is set to 0 for nonrecoverable output and to 1 for recoverable output.
See ATTDPN, ATTPRN, ATTRDPN and ATTRPRN, and ATTDQN and ATTDP for a more detailed description of these parameters. In the ATTACH topic, these parameters are prefixed by ATT rather than SCD. The rules for operation of these SCHEDULER parameters are the same as the rules defined for the ATTACH parameters.
