Note: If the program has been link-edited as reentrant with
AMODE(31),RMODE(ANY), the EXECUTION_KEY option is ignored,
and it is loaded into the extended readonly DSA (ERDSA). For details of
the type of storage allocated for the ERDSA, see the RENTPGM system
initialization parameter.
EXECUTION_SET(DPLSUBSET|FULLAPI)
specifies whether CICS is to link to and run the program as if it were running in
a remote CICS region.
Note: EXECUTION_SET applies only to local program definitions. Its purpose
is to test programs in a local CICS environment as if they were running
as DPL programs.
DPLSUBSET
CICS links to and runs the program with the API restrictions of a
remote DPL program. The program can use only a subset of the
CICS API.
FULLAPI
CICS links to and runs the program without the API restrictions
of a remote DPL program. The program can use the full CICS
API.
PROGRAM_ATTRIBUTE(RELOAD|RESIDENT|REUSABLE|TRANSIENT)
specifies the residency status of the program—that is, when its storage is to be
released.
RELOAD
The program is not reusable, and therefore several copies may be
loaded. A copy is removed from storage when a RELEASE_PROGRAM
call (for that copy) is issued.
RESIDENT
At any one time there will be no more than a single copy of the
program in storage, and this will not be removed unless deleted.
RESIDENT programs must be at least quasireentrant. Any program of
PROGRAM_TYPE SHARED is RESIDENT by default.
REUSABLE
Similar to RESIDENT, except that a REUSABLE program that is not in
use can be removed from storage by CICS, for storage optimization
reasons.
TRANSIENT
Similar to RESIDENT, except that a TRANSIENT program is removed
from storage as soon as its user count drops to zero.
PROGRAM_NAME(name8 | string | 'string')
specifies the name of the program whose attributes are to be changed.
name8
The name of a location containing an 8-byte program name.
string A string of characters naming the program.
'string'
A string of characters in quotation marks. The string length is set to 8
by padding with blanks or truncating.
PROGRAM_TOKEN(name4)
specifies a token identifying the program.
