4. If	the continuation handle field in the	receiver variable is not
the	following steps until the continuation	handle equals blanks:

a. Copy the continuation handle from the receiver variable to the c handle parameter.

	b. Call	the	API again by		using		the continuation handle			that is retur
	all	other	parameters	the		same	as	the	original API	call.
For	a program		example that	uses		a continuation handle, see “Retrieve Ex
and	Exit	Program Information—ILE			C	Example”		on	page 4-13.

Domain Concepts

All objects are assigned a domain attribute when domainthey areis acreated. A characteristic of an object that controls how programs can access the set, the domain remains in effect for the life of the object. The butes aresystem anduser.

Most object types on the			system		are	created	in system domain. When y
your	system	at security	level	40	or	50, system	domain objects can be
only	by using	the commands	and	callable		APIs provided.

These object types can be either system or user domain. The list inc symbolic object type.

Ÿ User space (*USRSPC)

ŸUser index (*USRIDX)

ŸUser queue (*USRQ)

Objects of the type *USRSPC, *USRIDX, and *USRQ in the user domain ca manipulated directly by MI instructions without using the system-provided commands.

Note:	Objects of the	type *PGM,	*SRVPGM, and	*SQLPKG also can be		in	the
	user domain. Their contents cannot be manipulated directly					by MI
	instructions.
Prior	to Version 2 Release 3 Modification			0,	all user objects were c
user	domain. Starting in	Version 2	Release	3	Modification 0, user		objec

in either the user domain or the system domain. The allow user domain (QALWUSRDMN) system value determines which libraries can contain user-domai user objects. The default QALWUSRDMN system value is set to *ALL, but c changed by system administrators on individual machines to be one libra of libraries. If your application requires direct pointer access to objects in a library that is not specified in the QALWUSRDMN value, y

administrator		can	add the library to the system value.
The	ability	to	create user	domain objects on	a	system	with a	securi
is	controlled	by the allow user domain (QALWUSRDMN)				system	value. See the
table in the		description of		the Create User	Queue (QUSCRTUQ)System			API in
API	Referencefor		more information.
