You can supply VSAM exit routines to do the following
tasks:
You can use the EXLST VSAM macro to create an exit list. EXLST parameters EODAD, JRNAD, LERAD, SYNAD and UPAD are used to specify the addresses of your user-written routines. Only the exits marked active are executed. For information about the EXLST macro, see z/OS DFSMS Macro Instructions for Data Sets. You can use access methods services commands to specify the addresses of user-written routines to perform exception processing and user-security verification processing. For information about exits from access methods services commands, see z/OS DFSMS Access Method Services Commands. Table 1 shows the exit locations available from VSAM.
