(was ...SWDAEPA) I have a number of CSECT in my main module I always do a link eploc= to every CSECT First thing I do at every CSECT is establish An Estae passing parms such CSECT name And retry address I also always use the same base register And have a branch around eyecatcher of CSECT name and date In my standard recovery which I use for all my code if don’t find a sdwaname I do chain the rb comparing the CSECT name to the CDENAME I do check if it’s a major or minor CDE since in my code it’s typically minor This seems to work when I have gotten abends and by work I mean I have eventually been able to retrieve my registers I also delete the Estae on the way out if the CSECT I didn’t see this method in any IBM books Or share So I am asking Peter yourself if it’s good practice > On Aug 17, 2022, at 10:28 AM, Seymour J Metz <sme...@gmu.edu> wrote: > > Is "the user's code" only the code that did the ESTAE or also the subroutine > that it called? > > > -- > Shmuel (Seymour J.)
