Console Commands

The commands given here are from the 1974 VM/370 point of view and an effort has been made
 to point out things that are different from newer versions of this OS.  Please email me with
suggestions or corrections.  Hopefully computer hobbyist will find this guide usefull.

There are four componets of VM/370, each of which has it's own command language.  They are:
CP	IBM Virtual Machine Facility/370: CP Command Reference for General Users
CMS	IBM Virtual Machine Facility/370: CMS User's Guide
	IBM Virtual Machine Facility/370: CMS Command and Macro Reference
RSCS    VM/370: Remote Spooling Communications Subsystem (RSCS) User's Guide
IPCS    VM/370: Interactive Problem Control System (IPCS) User's Guide

Below is a brief table of common CP and CMS commands.

CP Commands

The terminal is in one of two modes, CP mode or VM mode.  Enter "TERMINAL MODE CP" or "TERMINAL MODE VM" to communicate with CP or the 
virtual OS respectively.
Commands are grouped into different privilege classes A thru H.
	A - System Operator
	B - System Resource Operator
	C - System Programmer
	D - Spooling Operator
	E - System Analyst
	F - Service Representative
	G - General User
	H - Reserved for IBM Use
