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

Usage Notes
IBMclass c
specifies that you only want to display information for the specific IBM class
associated with the specified CP command. The variable c is the IBM-defined
privilege class A, B, C, D, E, F, or G.
IBMclass 0
specifies that you only want to display information for CP commands with no
assigned IBM class. Only commands originally defined with privilege class
“ANY” have no assigned IBM class.
1. For each command, CP has at least 1 command table entry block. If the
command has more than 1 IBM class, CP has 1 command table entry block
for each version of the command. For example, the DEFINE command has 3
IBM classes: A, E, and G. To display information for the DEFINE GRAF
command, you want the command table entry block for the class G DEFINE
command:
query cpcmds define ibmclass g
The only exceptions to this are the QUERY and SET commands. CP has at
least 1 command table entry block for each QUERY and SET subcommand. To
display information for the QUERY TIMEZONES subcommand, you would
issue 1 of the following commands:
query cpcmds query subcmd timezones
query cpcmds query subcmd timezones ibmclass g
2. You can use the minimum abbreviation of the command or subcommand
name. For example, issuing either of the following commands produces the
same results:
query cpcmds query subcmd privclass
query cpcmds q subcmd priv
3. To define a new CP command or a new version (by IBM class) of an existing
CP command, use the DEFINE COMMAND or CMD command (page 134).
4. To define a new alias for an existing CP command, use the DEFINE ALIAS
command (page 119).
5. To load the command processing code into CP’s system execution space, use
the CPXLOAD command (page 101).
6. To activate a CP command:
v While defining it, use the ENABLE operand of the DEFINE COMMAND or
CMD command (page 134).
v After defining it, use the ENABLE COMMAND or CMD command (page
426).
7. To change the definition of an existing CP command, use the MODIFY
COMMAND command (page 599).
8. To deactivate a CP command:
QUERY CPCMDS
v While defining it, use the DISABLE operand of the DEFINE COMMAND or
CMD command (page 134).
v After defining it, use the DISABLE COMMAND or CMD command (page
263).
9. To remove the command processing code from CP’s system execution space,
use the CPXUNLOAD command (page 107).

Customization book.
