The process OWNER attribute is not really a AUTHORIZE piece of information;
instead, for a sub-process it returns the PID of the process that created
it, for a "top-level" process it returns the null string (no owner).

Try:   $ WRITE SYS$OUTPUT F$GETJPI("","PID")    ! display current process
then,  $ SPAWN                                  ! create a sub-process
then,  $ WRITE SYS$OUTPUT F$GETJPI("","OWNER")  ! display PID of owner
then,  $ LOGOUT                                 ! return to master process

Both WRITE statements will display the same PID.
