Identifying Entry Points

Every entry point name that is used as an RSCS exit routine must be identified to GCS. ALIAS statements in the link-edit control file identify the entry points that are used as an alias for a load module. In Figure 2, the entry point names SECURE00 - SECURE32 are aliases for the SECURE load module. As Figure 1 shows, aliases can also be specified at the top of the SECURE ASSEMBLE file.
Figure 1. Specifying Aliases in the Source Module (SECURE ASSEMBLE)
         PUNCH ' ALIAS SECURE00,SECURE01,SECURE14,SECURE15,SECURE19'
         PUNCH ' ALIAS SECURE21,SECURE32'
SECURE   RMOD  CRVBASE=TCRVTAB,CRVCALL=YES

You can use either method to specify the aliases; however, you can specify a maximum of 16 alias names in a load module. To identify more than 16 entry points in an exit package, you can divide the exit package into 2 or more load modules. You can also use the LOADCMD command and GCS IDENTIFY macro to identify the entry points to GCS.
