Appendix B. RSCS Control Areas This appendix lists the control areas used during task processing. !nfcr:aticn
such as lists of synchronous locks, channel Frogra.s, TAKE request tables and
buffers, and various work constants are included in these areas.
Appendix B. RSCS Centrel Areas 285
The AXS Monitor Control Area is a data area used by tMTAXS to set up synch locks, a TAKE request table, a TAKE request and response buffer, and an input tuffer.
