BLSRXSSP — Map the symbol service parameter list

Description

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

The symbol service enables exit routines to process symbols and obtain data represented by the symbols.

See z/OS MVS IPCS Customization for information about the symbol 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 BLSRXSSP data area.

Environment

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

Programming requirements

None.

Restrictions

None.

Register information

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

Performance implications

None.

Syntax

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

Syntax	Description

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

␢	One or more blanks must precede BLSRXSSP.

BLSRXSSP

␢	One or more blanks must follow BLSRXSSP.

DSECT=YES	Default: DSECT=YES
DSECT=NO

Note: Users must supply a label (name), and start it in column 1 of the BLSRXSSP macro. When the BLSRXSSP 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 symbol service parameter list is mapped with a DSECT (DSECT=YES) or a symbol service parameter list is mapped, but no DSECT is generated (DSECT=NO).

Example

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

XSSP   BLSRXSSP DSECT=NO
