Adding an entry to an access list z/OS MVS Programming: Extended Addressability Guide SA23-1394-00 |

The ALESERV ADD macro adds an entry to the access list. Two parameters
are required: STOKEN, an input parameter, and ALET, an output parameter.
Two optional parameters, AL and ACCESS, allow you to limit access
to an address/data space:
The ALESERV ADD process described in this section applies to the data spaces called SCOPE=SINGLE and SCOPE=ALL. For SCOPE=COMMON data spaces, ALESERV ADD adds an entry to all PASN-ALs. Creating and using SCOPE=COMMON data spaces describes the ALESERV ADD process for these data spaces. The ALESERV ADDPASN macro adds to the DU-AL an entry for the primary address space. An application would use this macro if its programs run in many address spaces. ALESERV ADD and ALESERV ADDPASN are the only ways to add
an entry to an access list. For examples of adding entries to the
DU-AL and PASN-AL, see:
The example of adding an entry for an address space specifies that the system is not to check for EAX-authority. If you want to know whether an address/data space already has an entry on an access list, use ALESERV SEARCH. As input to the macro, give the STOKEN of the space, which access list is to be searched, and the location in the list where you want the system to begin to search. If the entry is on the list, the system returns the ALET. If the entry is not on the list, the system returns a code in register 15. |
