z/VM: CP Commands and Utilities Reference - z/VM - IBM

Introduction
The minimum acceptable truncation is Q, but CP will accept any of these forms of
the command.
Abbreviations are also shorter forms of commands and operands, but unlike
truncations, are not formed by simply dropping letters from the end of the command
name.
Command syntax boxes show acceptable abbreviations for command names. The
abbreviations appear below the full name of the command. Operand abbreviations
are listed in the operand descriptions following the syntax box.
For example, the syntax box for the MESSAGE command shows:
Message
Msg
This means that you can:
v Truncate the command to a minimum of “M”
v Use the abbreviation “MSG”
v Truncate the abbreviation to “MS” or “M”.
Thus, CP accepts all of the following forms of the MESSAGE command:
message
messag
messa OR msg
mess ms
mes
me
m
m
How to Read Syntax Diagrams
4 z/VM: CP Commands and Utilities Reference
This book uses diagrams to show the syntax of external interfaces and statements.
Also, this book uses a special notation to show variable, optional, or alternative
content in examples of messages and responses.
To read a syntax diagram, follow the path of the line. Read from left to right and top
to bottom.
v The ►►─── symbol indicates the beginning of the syntax diagram.
v The ───► symbol, at the end of a line, indicates that the syntax diagram is
continued on the next line.
v The ►─── symbol, at the beginning of a line, indicates that the syntax diagram is
continued from the previous line.
v The ───►◄ symbol indicates the end of the syntax diagram.
Within the syntax diagram, items on the line are required, items below the line are
optional, and items above the line are defaults. See the following examples.
