CBLQDA (COBOL Only)

Derivation: COBOL QSAM Dynamic Allocation

CBLQDA controls COBOL QSAM dynamic allocation on an OPEN statement.

CBLQDA does not affect dynamic storage allocation for the message file specified in MSGFILE or the Language Environment formatted dump file (CEEDUMP).

Non-CICS default:: CBLQDA=((OFF),OVR)
CICS® default:: CBLQDA is ignored under CICS.


Syntax

                    .-OFF-.        .-OVR----.      
>>-CBLQDA--=--(--(--+-ON--+--)--,--+-NONOVR-+--)---------------><

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.
OVR: Specifies that the option can be overridden.
NONOVR: Specifies that the option cannot be overridden.

z/OS® UNIX considerations

Using CBLQDA(OFF) under z/OS 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.
