@BIND SUBSCH—helps the run unit

The @BIND SUBSCH statement performs the following:

• Signs on the run unit to the DBMS
• Identifies the location of optional user-specified IDMS and LRC communication blocks to the DBMS
• Names the subschema to be loaded for the run unit
• Names the Distributed Database System (DDS) node under which the run unit will execute
• Identifies the database to be accessed

You must code the @BIND SUBSCH statement as the first DML statement in the program that is passed to CA IDMS/DB at execution time. This statement must be first both logically and physically; you cannot branch to @BIND SUBSCH.

In most cases, specific designation of @BIND SUBSCH within an application program is not necessary since the @COPY IDMS,SUBSCHEMA-BINDS statement (see @COPY IDMS) automatically invokes the necessary @BIND statements.

Note: If program registration is in effect, the @COPY IDMS,SUBSCHEMA-BINDS statement is required to properly assign the programs to the subschema control block. Individual @BIND SUBSCH and @BIND REC statements should not be used if program registration was enabled during system generation.
