Derivation: COBOL QSAM Dynamic Allocation

CBLQDA controls COBOL QSAM dynamic allocation on an OPEN statement.

The default value for non-CICS applications is CBLQDA(OFF).

CBLQDA is ignored under CICS®.

Syntax

              .-OFF-.      
>>-CBLQda--(--+-----+--)---------------------------------------><
              '-ON--'      

OFF

Specifies that COBOL QSAM dynamic allocation is not permitted.

ON

Specifies that COBOL QSAM dynamic allocation is permitted. ON conforms to the 1985 COBOL standard.

Usage notes

• CBLQDA(OFF) is the recommended default because it prevents a temporary data set from being created in case there is a misspelling in your JCL. If you specify CBLQDA(ON) and have a misspelling in your JCL, Language Environment creates a temporary file, writes to it, and then z/OS® deletes it. You receive a return code of 0, but no output.
• CBLQDA does not affect dynamic allocation for the message file specified in MSGFILE or the Language Environment formatted dump file (CEEDUMP) .
