$! RESET.COM
$! Emulate the TOPS-20 RESET command
$! GMU	19-Aug-83 09:35	Version 2.02
$!
$! Command syntax is:
$!
$!	$ RESET				;For current process
$!	$ RESET .			;For current process
$!	$ RESET *			;For all processes
$!	$ RESET name			;For specific process
$!
$! If a specific process name is given, only enough must be specified
$! to make it unique.
$!
$! Find the PID and name of the top-level owner process
$!
$ owner_pid = f$pid(0)			! Get pid of current process
$!
OWNER_PID_LOOP:
$ pid = f$getjpi(owner_pid,"owner")	! Get pid of owner
$ if pid .eqs. "" then goto owner_pid_end ! pid is null if no owner
$ owner_pid = pid			! Make that the new owner
$ goto owner_pid_loop			! Try again
$!
OWNER_PID_END:

     p1 .eqs. "." then goto done	! RESET . is a no-op
$!
$! Loop over all processes in this job getting their names.  If the name
$! matches the process name given as the argument to the command, or if
$! the argument was a "*", stop the process.
$!
$ p1_length = f$length(p1)		! Get length of process name
$ context = ""				! Cycle through process names
$!
RESET_LOOP:
$ pid = f$pid(context)			! Get next pid in this process
$ if pid .eqs. "" then goto done	! F$pid returns null when done
$ if owner_pid .eqs. pid then -		! If this is the top process,
$	goto reset_loop			!   don't kill is (it's a logout)

     p1 .eqs. f$extract(0,p1_length,"''upper_proc_name'") then -
	goto kill_process		! If name matches, kill it
$ goto reset_loop			! Try next process name

$! Here when we found a process that we want to kill.
