BLSRXMSP — Map the storage map service parameter list

Description

BLSRXMSP maps the storage map service parameter list. Use this parameter list when calling the storage map service from within an installation-written interactive problem control system (IPCS) exit routine.

The storage map service allows exit routines to process storage map entries and to obtain data represented by the storage map entries.

See z/OS MVS IPCS Customization for information about the storage map service. See z/OS MVS Data Areas in z/OS Internet Library at http://www.ibm.com/systems/z/os/zos/bkserv/ for a mapping of the BLSRXMSP data area.

Environment

Because BLSRXMSP is not an executable macro, there are no specific environment requirements.

Programming requirements

None.

Restrictions

None.

Register information

Because BLSRXMSP is not an executable macro, there is no need to save and restore register contents.

Performance implications

None.

Syntax

The standard form of the BLSRXMSP macro is written as follows:

Syntax	Description

`name`	`name`: Symbol. Begin `name` in column 1.

␢	One or more blanks must precede BLSRXMSP.

BLSRXMSP

␢	One or more blanks must follow BLSRXMSP.

DSECT=YES	Default: DSECT=YES
DSECT=NO

Note: Users must supply a label (name), and start it in column 1 of the BLSRXMSP macro. When the BLSRXMSP macro is processed, the label becomes the record name and the prefix to the name of each field in the record.

Parameters

The parameters are explained as follows:

DSECT=YES
DSECT=NO: A storage map service parameter list is mapped with a DSECT (DSECT=YES) or a storage map service parameter list is mapped, but no DSECT is generated (DSECT=NO).

Example

Code the following to map the storage map service parameter list, but not as a DSECT. All fields will appear with the prefix XMSP.

XMSP   BLSRXMSP DSECT=NO
