The @SSLRCTL statement is an Assembler macro instruction that generates source data description code for the LRC block. @SSLRCTL must be used in place of the @COPY IDMS,SUBSCHEMA-LR-CTRL statement when the DML precompiler is not used.
Syntax
►►─── @SSLRCTL ─┬───────────────────────────────┬─────────────────────────────►◄ └─ LRSIZ=lr-control-block-size ─┘
Parameters
Specifies the size of that portion of the LRC block that contains information about the logical-record request's WHERE clause.
Defaults to 576 bytes; if included, it should specify a size large enough to accommodate the most complex WHERE clause in the program. (For the algorithm for calculating lrc-block-size, see @COPY IDMS earlier in this chapter.)
