@BIND SUBSCH Parameters

SUBSCH=

Signs on the application program to CA IDMS/DB.

subschema-name

Identifies the subschema in use. The run unit uses the standard IDMS communications block brought previously into the program by compiler-directive statements.

PGMNAME=program-name

Identifies the user program.

LRC=lrc-block-location

Identifies the address of a logical-record request control (LRC) block other than that brought into the program by the DML precompiler. The definition of this user-specified subschema control area must be consistent with the standard SSLRCTL block as normally invoked and used.

LRSIZ=lrc-block-size

Specifies the size of that portion of the LRC block that contains information about the request's WHERE clause. Lrc-block-size defaults to 576 bytes. For the algorithm for calculating lrc-block-size, see @COPY IDMS.

DBNAME=

Identifies the database to be accessed by the program. If this parameter is specified, database-name may be overridden by IDMSOPTI module or SYSCTL file specifications.

database-name

Must specify a register that points to the name of the database, a 1- to 8-character field, or a quoted literal.

DBNODE=

Optionally names the node that will service database requests issued by the program. If this parameter is specified, nodename may or may not be overridden by IDMSOPTI module or SYSCTL file specifications (z/OS and OS/390 only).

nodename-pointer

Must be a register that points to the name of the node, a 1- to 8-character field, or a quoted literal.

DICTNAM=

The dictionary that contains the subschema.

dictionary-name-pointer

Either a register that points to the field that contains the dictionary name or a quoted literal.

DICTNOD=

The dictionary node that contains the subschema.

dictionary-nodename-pointer

Either a register that points to the field that contains the name of the dictionary or a quoted literal.
