Use this publication as a reference manual;
it contains all of the command formats,
syntax rules, and operand and option for CMS commands, subcommands,
and macro instructions for general users.
The Fa£ili!YlJIQ: Guide, GC20-1819, contains information and functional
descriptions of CMS commands, as well as
information on using the editor, EXEC, and
debugging facilities of CMS. You should be
familiar with the contents of the before you attempt to use
this manual. For most of the CMS commands described in this publication, you
may find additional useful notes in the publication has six sections: "Section 1. Introduction and General
Concepts" describes the components of the VM/3 7 0 system and tells you how to enter CMS commands. It lists the notational
conventions used in this manual, so that
you can interpret the command format in Section 2. Section 1 also
contains information about the CMS command
search Jrder and a summary of all the eMS commands available under VM/370, including
those not for general users. "Section 2. CMS Commands" contains
complete format descriptions, and operand
and option lists, for the CMS commands
available to general users. Each command
description contains usage notes, and lists
responses and error messages (with
associated return codes} produced by the
command. "Section 3. EDIT subcommands and Macros"
describes the sub commands and macros
available in the environment of the CMS editor, which you can invoke with the EDIT
command. Each subcommand description
contains usage notes and summarizes the types of responses you might receive.
Where applicable, additional information is provide1 for users of display terminals. "Section 4. DEBUG Subcommands" describes
the sub commands available in the debug pnvironment of CMS. Each subcommand contains usage notes and, where
applicable, lists the responses to the
su bcomma nd.
Preface "Section 5. EXEC Control statements"
describes the control statements, special
variables, and built-in functions you can
use when you create EXEC procedures to
execute in eMS. The control statement
descriptions contain usage notes, where
applicahle. "Section 6. CMS Macro Instructions"
lists the formats and operands of the eMS assembler language macro instructions you
can use when you write programs to execute
in CMS. This publication
appendixes:
also has three A: Reserved Filetype Defaults"
lists the filetypes that are recognized by
the CMS editor and indicates the default
settings that the editor supplies for
logical tabs, truncation, verification,
logical record length, and so on.
"Appendix B: DOS/VS Access Method Services and VSAM Functions Not Supported in CMS" lists the restrictions on the use
of access method services and VSAM in the CMS/DOS of CMS. "Appendix c: as/vs Access Method Services and VSAM Functions Not Supported in CMS" lists the restrictions for as
programmers using access method services
and VSAM in eMS. Some of the following convenience terms are
used throughout this publication: The term "eMS/DOS" refers to the
functions of CMS that become available

you are using, including procedures for
gaining access to the VM/310 system and
logging on, see the GC20-1810. If you are using an IBM 3761
Communications Terminal, the IBM GA18-2000, is a
prerequisite. The CP commands that are available to
you as a general user are described in
IBM Virtual Machine GC20-1820. For additional tutorial information on
using CM, you may want to use IQf = ! SR20-4438. If you are going to use an IBM Program
