ACTION=

The action to be taken:

ADD | DELETE

Specifies that JES2 is to add (ADD) or delete (DELETE) an ALET.

Note: You must also specify one and only one of the following: DSB=, HASXB=, NAME=, or NAMEFLD=.

DSB=

Specifies the address of the data space block (DSB) associated with the data space for which you want an ALET added or deleted.

If you specify DSB=, you cannot specify HASXB=, NAME=, or NAMEFLD=.

HASXB=

Specifies the address of the address space extension block (HASXB) for which a DELETE ALL is required. HASXB= implies NAME=ALL and can only be specified on a ACTION=DELETE call.

If you specify HASXB=, you cannot specify DSB=, NAME=, or NAMEFLD=.

NAME=

Specifies the name of the ALET requested. This name must match either the name specified on a $DSPSERV CREATE call or one of the predefined names in $ALINDEX. NAME=ALL requests that JES2 delete all ALETs. NAME=ALL can only be specified on a ACTION=DELETE call.

If you specify NAME=, you cannot specify DSB=, HASXB=, or NAMEFLD=.

NAMEFLD=

Specifies a label that contains the name of the ALET or a register that points to the name of the ALET to be processed. This name must match either the name specified on a $DSPSERV CREATE call or one of the predefined names in $ALINDEX. A field that contains the value ALL is equivalent to specifying NAME=ALL and only allowable on a ACTION=DELETE call.

If you specify NAMEFLD=, you cannot specify DSB=, HASXB=, or NAME=.

ERRET

The label to branch to in the event of a non-zero return code.

OKRET

The label to branch to if the return code is zero.

• If JES2 has already added a requested ALET, a new ALET is not added.
• If the ALINDEX does not exist, JES2 creates it on the first ADD call.
• If this is a DELETE call and NAME=ALL (or implied), JES2 deletes the ALINDEX table.
• If all ALETs in the ALINDEX table are deleted, the table is not also deleted.

• JES2 main task, subtask, functional subsystem (HASPFSSM), or user environment.
• $WAIT cannot occur.
• Callers can be in AR ASC mode.
