JIB Jab
VAXman-
How do you get the JIB from the PID using DCL such that you can see the JOB
logical table of the process whose PID you've specified. Have fun...

you say "using DCL" ... I do have a macro routine that I call from a
wrapper program in Basic (Vax, Alpha and IA64 versions) that when
given
a PID, will look it up and create a symbol containing a string
like LNM$JOB_82DE6580 ... got help on writing this from several
people,
not something I was able to figure out on my own :-)
GETJOB == "$PAGE_C:[003]GETJOB.ALPHA_EXE"
getjob 'f$integer(%x1B37DC57)' xyz
SHOW SYMBOL xyz
XYZ = "LNM$JOB_82DE6580"
wiil that do ??

I could write such a program in my sleep.

The question was to get it in DCL. No escape hatch to a $CMKRNL hack.

Here is my entry:

The job table for process 0000046D is LNM$JOB_884F9D00

That seems like a lot of work. How about:
$ show log/structure lnm$job
"LNM$JOB" = "LNM$JOB_886E6300" (LNM$PROCESS_DIRECTORY)
Tim E. Sneddon
But the challenge was for any PID. My procedure simply defaults
to the current process (as do most system services, etc. that
deal with process specific information).
If you supply any PID as argument P1 my procedure will track down
its job logical table name.
Tim.
VAXman-
Yeah Tim, I believe that escape to SDA is the only way. I don't understand
why the $GETJPI system service doesn't have the JIB as one of its item list
codes.
VAXman-
If you can make that work for a process other then your own, do let us know.
