If an "attached" task has terminated, there should be nothing in your dump related to it. The BR 14 in the task should branch to an operating system routine to post the ECB and perform the appropriate housekeeping. The only thing in your dump should be the ECB. The mother and daughter tasks both compete for execution time independently. The code following the ATTACH(X) macro can execute before or after any portion of the attached task. If you need the mother task to wait on the daughter, it is your responsibility to WAIT on the ECB.
If a "linked" routine follows normal save area conventions, then in the save area you passed it in R13 you should be able to find the contents of R14. This is where the BR 14 instruction should return if you remembered to restore the registers before branching. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Donald Likens Sent: Friday, July 01, 2011 12:18 PM To: [email protected] Subject: Real return address for link and attach I have a situation where my subtask terminates and it seems it returns to somewhere in my program and starts executing my primary task (hard to believe isn't it). I want to check out my theory by determining in a dump where the attachx is going to return to after I execute the BR 14 (and return to attachx). I would also like to know where LINK(LINKX) is returning to when I execute the BR 14 (and return to link). Please help. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
