Request Buffer for Standard Subsystem Operations

Table 1 shows the request buffer layout for standard subsystem operations:

Table 1. Request Buffer Layout for Standard Subsystem Operations. Length represents the maximum length if the format is variable.
Field	Length	Format Fixed/Variable	Value	Obtained From
Request ID	8	F	EVJESPRQ	constant
delimiter	1	F	blank	constant
Application name	16	V	variable	ADNAME
delimiter	1	F	blank	constant
Workstation name	4	F	NVnn	WSNAME
delimiter	1	F	blank	constant
Operation no	3	V	1 – 255	OPNO
delimiter	1	F	blank	constant
Job name	8	V	variable	JOBNAME
delimiter	1	F	blank	constant
Request	8	V	variable	first field in TXTOP
delimiter	1	F	blank	constant
Parameter 1 (optional)	*	V	variable	second field in TXTOP
delimiter	1	F	blank	constant
Parameter 2 (optional)	*	V	variable	third field in TXTOP

Note: The length of Parameter 1 or 2 is from 1 to 8 characters.

Table 2 shows the request buffer layout for non-subsystem user extension (UXaaaaaa) operations:

Table 2. Request Buffer Layout for Non-Subsystem, User Extension (UXaaaaaaa) Operations. Length represents the maximum length if the format is variable.
Field	Length	Format Fixed/Variable	Value	Obtained From
Request ID	8	F	EVJESPRQ	constant
delimiter	1	F	blank	constant
Application name	16	V	variable	ADNAME
delimiter	1	F	blank	constant
Workstation name	4	F	NVnn	WSNAME
delimiter	1	F	blank	constant
Operation no	3	V	1 – 255	OPNO
delimiter	1	F	blank	constant
Job name	8	V	variable	JOBNAME
delimiter	1	F	blank	constant
Request	24	V	variable	TXTOP

Any parameter with a variable length is left-adjusted and all trailing blanks are ignored.
