If you really want it, the JIB address is stored in the PCB >at offset PCB$L_JIB. Well, I really do want it! I think many people here have gotten a bit too comfortable with all their privs. I am forced to use the JOB table because there is NO other table to which I have access to write other than my own. Because it is possible to set ACL's on job tables, it would be really nice if there were a way to fetch the name of the table also. I don't have any of these wonderful privs SYSNAM, GRPNAM, CMKRNL, SYSPRV, so it is very difficult to extract the name of a foreign processes job table name. I also don't have GROUP or WORLD priv so I am even limited to my own tables. A nice feature available in SHOW is the SHOW LOGICAL /STRUCTURE command which will show all the tables currently accessible. I bet any system manager doesn't use this a lot because it might be a few pages long... Users, on the other hand, only get the standard ones... proc, job, group, sys I tried using the offset, I am not sure but I think the explicit address that I got was %x80135430 (which was not the table name either) but I had no read access to that area of virtual memory. I hope DEC straightens some things out. I don't understand what was wrong with using the top level process on the process tree PID ... that would be unique wouldn't it? I am still wondering about how to get it, through some table lookup or a system service. JPI would be nice, but if there are other ways, please let me know. Thanks, I appreciate all the replys on this topic!! -- Jeff Capehart Internet: micronaut%oak.decnet@pine.circa.ufl.edu University of Florida UUCP: ..!ihnp4!codas!ufcsv!beach.cis.ufl.edu!jdc
