Library /sys$common/syshlp/sda.hlb SHOW, PROCESS, /INDEX=n  *Conan The Librarian (sorry for the slow response - running on an old VAX)

     Displays the software and hardware context of the process which is
     specified by the index of the software PCB into the system's PCB
     vector.  Alternately,  this value could be the process identifica-
     tion ( PID or EPID ), from which SDA extracts the correct index.
