Link-editing linkage-assist routines z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO SA23-1375-00 |

Linkage-assist routines provide the connection between your program and the system services that your program requests. When using callable services, link-edit the appropriate linkage-assist routines into your program module so that, during execution, the linkage-assist routines can resolve the address of, and pass control to, the requested system services. You can also dynamically link to linkage-assist routines as an alternative to link-editing. For example, issue the LOAD macro for the linkage-assist routine, then issue a CALL to the loaded addresses. To invoke the linkage-editor or binder, code JCL as in the following
example:
Note: Omitting NCAL from the linkedit parameters (as the
example shows) and specifying SYS1.CSSLIB in the //SYSLIB statement,
as shown, causes the addresses of all required linkage-assist routines
to be automatically resolved. This statement saves you the trouble
of having to specify individual linkage-assist routines in INCLUDE statements.
