BLSRESSY — Map IPCS symbol table data

Description

BLSRESSY maps a structure that is part of the interface between an interactive problem control system (IPCS) exit service and an IPCS exit routine. See z/OS MVS IPCS Customization for information about IPCS exit services. 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 BLSRESSY data area.

Environment

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

Programming requirements

None.

Restrictions

None.

Register information

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

Performance implications

None.

Syntax

This is the standard form of the BLSRESSY macro:

Syntax	Description

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

␢	One or more blanks must precede BLSRESSY.

BLSRESSY

␢	One or more blanks must follow BLSRESSY.

DSECT=YES DSECT=NO	Default: DSECT=YES

ABITS=31	Default: ABITS=31
ABITS=64

Note: Users must supply a label (name), and start it in column 1 of the BLSRESSY macro. When the BLSRESSY macro is executed, 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: Specifies whether the record mapped by BLSRESSY is to be mapped as a DSECT (YES) or not (NO).
ABITS=31
ABITS=64: Specifies whether the record mapped by BLSRESSY is to be mapped as 31-bit or 64-bit.

Example

Map the IPCS symbol table record but not as a DSECT.

ESSY    BLSRESSY DSECT=NO
