FLTAREA: Keep or Free the Filter Save Area

FLTAREA=KEEP: Specifies keeping the filter save area. Code this operand if the RESUME function might be called later (to resume processing prematurely terminated because the number of caller-supplied buffers is not enough to contain all the returned DSCBs).
CVAFFILT returns the address of the kept filter save area in the CVAFFILT parameter list (CVFSA field). If you specify the same parameter list in subsequent RESUME calls, CVAFFILT reuses the same filter save area.

Tip: If you code this operand, you must subsequently issue CVAFFILT with ACCESS=RLSE to release the filter save area.
FLTAREA=(KEEP,addr or (reg)): Supplies the address of a previously obtained filter save area. See the description of FLTAREA=KEEP operand for additional concerns.
FLTAREA=NOKEEP: Frees the filter save area upon completion of the CVAF request.
FLTAREA=(NOKEEP,addr or (reg)): Frees a previously obtained filter save area upon completion of the CVAF request.
