This publication contains descriptions of major data areas and control blocks used by the three major components of V"/370. The
threecOllponents are: I • The Control Prograll (CP) I • The Conversational Monitor System (CMS) I • The Remote Spooling I Subsystem (RSCS) Comllunications There are three sections
appendixes, as follows:
and five• "Section 1. CP Data Areas and Control Blocks" contains information about CP data areas and control blocks. • "Section 2. CMS Data Areas and Control BloCKS" contains information on CMS data
areas and control blocks.• "Section 3. RSCS Data Areas and Control Blocks" contains information on RSCS data areas and control blocks. • "Appendix A. CP and RSCS Equate Symbols" contains assembler language equate symbols used by CP and RSCS to reference
data.• "Appendix B. RSCS Control Areas"
