Syntax

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

OFF

Suppresses the COBOL batch debugging features.

ON

Activates the COBOL batch debugging features.

You must have the WITH DEBUGGING MODE clause in the environment division of your application in order to compile the debugging sections.

OVR

Specifies that the option can be overridden.

NONOVR

Specifies that the option cannot be overridden.

Performance considerations

Because DEBUG(ON) gives worse runtime performance than DEBUG(OFF), use it only during application development or debugging.
