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

Some commands require no operands; others require several. You can find a
description of each command with all of its operand requirements in Chapter 2, “CP
Commands” or Chapter 3, “CP Utilities.”
Unless otherwise indicated, you must enter the operands you select in the order in
which they appear in the command format.
How to Enter Comments in the CP Command Language
You can use the CP asterisk (*) command to annotate your display screen and
console spool file. (Within this file are your input to the system and the system’s
response to you.) Refer to “ASTERISK (*)” on page 12 for complete details.
Character Sets
You can enter CP commands using a combination of characters from 6 different
character sets. The contents of each of these sets is summarized in Table 1.

Using Truncations and Abbreviations
To make entering commands on the keyboard more convenient, VM lets you enter
many commands and operands in a shortened form. This shortened form can be
either a truncation or an abbreviation.
You truncate a command or operand name by dropping one or more letters from
the end of the name. The syntax box for each command shows the truncations you
can use for each command and its operands. If a letter appears in uppercase in the
syntax box, you must enter it when you enter the command from your display; if a
letter is in lowercase, you may omit it when you enter the command.
For example, the syntax box for the QUERY command shows the command as:
Query
This means that you can enter the QUERY command in any of the following forms:
query
quer
que
qu
q
