This is going to sound weird. It is in conjunction with some other strangeness that I am considering. But I need to create a z/OS task in my TSO region which does not "go away" (abend) when the TSO command which starts it terminates. I.e. it would be a "TSO DAEMON" to mix TSO and UNIX terminology. What I think I can do is have my TSO command back up the TCBOTC fields until I found the TCB whose TCBRBP points to the RB running IKJEFT01. I can then schedule an IRB to run under than TCB which will do an ATTACH of my "daemon" code. The problem at this point is that I am fairly sure that there is no way for my "daemon" task to shutdown normally when the user does a LOGOFF command, which would result in an A03 abend. I don't really mind that myself, but it is "not elegant". My next thought is to do the previous, but use the TCBFSA for that TCB in order to modify the saved value of R14 so that I can insert my own code into the shutdown for IKJEFT01. I'm not sure this will really work. That is, I'm not sure IKJEFT01 shuts down using a standard RETURN instead of, say, SVC 3.
What I want is a subtask which is started up either from the TSO READY or from ISPF option 6 or the TSO command in ISPF which will "stay around" until the TSO user either runs another "shutdown" TSO command or the standard TSO LOGOFF command. This subtask is a "communications end point" for another address space so that a TSO command can send a message and receive a response from that "server". It's not really a "server". But I'm still in the "vaguely mulling things around" stage, so I can't be more exact. John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
