.b 3
The ITEM macro will allocate the appropriate item list structure.
.b
If ^&bufaddr\& is not specified, 0 is assumed.
.b
For example:
.b
.lt
	get_jpi_list:
		ITEM	12,jpi$_username,username,username_length
		ITEM	4,jpi$_uic,uic,uic_length
		.long	0
.el
.b
would generate the following code for a call to the $GETJPI System Service:
.b
.lt
	get_jpi_list:
		.word	12
		.word	jpi$_username
		.address	username
		.address	username_length
		.word	4
		.word	jpi$_uic
		.address	uic
		.address	uic_length
		.long	0
.el
.b
and: 
.b
.lt
	file_scan_list:
		ITEM	0,fscn$_name
		ITEM	0,fscn$_type
		ITEM	0,fscn$_version
		.long	0
.el
.b
would generate the following code for a call to the $FILESCAN System Service:
.b
.lt
	file_scan_list:
		.word	0
		.word	fscn$_name
		.address	0
		.word	0
		.word	fscn$_type
		.address	0
		.word	0
		.word	fscn$_version
		.address	0
		.long	0
