Subschema Variables

The subschema variables (&R, &D, &A, &S, &T, and &Q) can appear in any CA IDMS DML or CA IDMS DMLO command where an entity of the type represented by the variable is appropriate.

Variable entities are:

• &R-RECORD which is current of transaction.
• &D-RECORD most recently displayed; not necessarily the same as &R.
• &A-AREA associated with whatever record is mentioned in the CA IDMS DML command, or if no RECORD is mentioned, the AREA associated with current RECORD of transaction.
• &S-SET most recently mentioned in any CA IDMS DML command.
• &T-SCRATCH AREA ID most recently mentioned in any CA IDMS DML command.
• &Q-QUEUE ID most recently mentioned in any CA IDMS DML command.

The SHOW VARIABLES command may be used to display current values of &R, &D, &A, and &S.
