The exit from an ATTACH is SVC 3. BR 14 takes you to CVTEXIT. If the task was attached with the ECB= or EXTR= operands, it is not removed from virtual storage until a DETACH is issued. I've never looked at a dump at that point in time, but I think that means that the TCB is still there. >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.

The return from the linked routine also takes you to CVTEXIT, which is an SVC 3 instruction. The SVC will delete the SVRB and return control to the RB that was active when the LINK was issued. -- Tom Marchant ---------------------------------------------------------------------- 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
