Privilege Class: C, E
Use LOCATE XITBK to display the real address of the CP exit block for a specific
exit point.
exit
exit1-exit2
is the number of the CP exit block whose real address you want to display.
Each exit must be a hexadecimal number between X'0000' and X'FFFF'. You
can specify a single exit number, a range of exit numbers, or any combination
thereof.
1. CP creates CP exit blocks for exit points when you issue the ASSOCIATE EXIT
command (page 18) to associate one or more entry point names or external
symbols with that exit point. If no one issued the ASSOCIATE EXIT command,
there is no CP exit block for CP to locate and CP issues error message
HCP2752E.
After creating a CP exit block, CP will not erase that CP exit block until the next
IPL. Disabling the exit point affects certain fields in the CP exit block, but does
not erase it. Disassociating the entry point names and external symbols erases
those fields in the CP exit block, but does not erase the CP exit block itself.
2. To display status and usage statistics information about a specific exit point, use
the QUERY EXITS command (page 791).
3. To display the real address of the CP indirect call locator block for a specific exit
point, use the LOCATE ICLBK command (page 539).
4. For more information about user-defined exit points, see the z/VM: CP Exit
Customization book.
