epname
Privilege Class: C, E
Use LOCATE ICLBK to display the real address of the CP indirect call locator block
for a specific entry point.
epname
is the name of the entry point whose CP indirect call locator block address you
want to display. The variable epname must be a 1- to 8-character string. The
first character must be alphabetic or one of the following special characters:
dollar sign ($), number sign (#), underscore (_), or at sign (@). The rest of the
string can be alphanumeric characters, the 4 special characters ($, #, _, and
@), or any combination thereof.
You can use generic entry point names to request information about a specific
subset of entry point names. A generic entry point name is a 1- to 8-character
string with asterisks (*) in place of 1 or more characters and percent signs (%)
in place of exactly 1 character. For example,
locate iclbk hcp%rc*
lists all the entry points that start with HCP and have RC as their fifth and sixth
characters.
1. To load customer-written CP routines into CP’s system execution space, use the
CPXLOAD command (page 101).
2. To add to, change, or replace the list of entry points and external symbols
associated with an exit point and to enable or disable that exit point, use the
ASSOCIATE EXIT command (page 18).
3. To display usage statistics information about indirect calls to external entry
points, use the QUERY ICLNAME command (page 824).
4. For more information about the indirect call locator block, see the z/VM: CP Exit
Customization book.
