Victor, Just how urgent is the need for your subsystem to perform the field obfuscation you discussed here last month?
Try looking at macro IEFSSDA in SYS1.MODGEN. Those subsystem function codes (16-19) should get you moving again. As for the SMS comment... that's a good question. SMS is a subsystem, so you are wanting to insert your subsystem ahead of (or behind) SMS; At any rate you want to be in between the user and the data. Maybe you'll want to consider something like what BLSR does (redirection of the JCL) to avoid the collision. (There are other ways, too.) (Do you see why several folks were pointing you at the possibility of an OPEN SVC intercept?) -- Tom Schmidt Madison, WI On Tue, 4 Apr 2006 12:56:38 -0400, Gil, Victor x28091 wrote: >I am probably missing something obvious - > >When setting up a subsystem, how do I tell the system to call a custom >function to Allocate, Open, Get, Close or Deallocate a dataset? > >Doesn't the association come from a table built using the IEFSSVTI macro? >But the list of codes "SSI Function Codes Your Subsystem Can Support" has >no such functions.
