	TITLE	KILL	PROGRAM TO STOP AND KILL USER JOBS
	SUBTTL	DAVID I. BELL/DIB/TARL



;THIS PROGRAM IS INTENDED TO LET USERS KILL THEIR OWN JOBS
;WITHOUT HAVING TO ASK AN OPERATOR TO DO IT.  KILL MAKES THE
;NECESSARY PRIVILEGE CHECKS, AND IF IT IS SAFE TO DO SO, IT
;WILL PROCEED TO STOP, DETACH, ATTACH, OR KILL OTHER JOBS FOR
;THE USER.  IN ADDITION, IT HAS FUNCTIONS WHICH ALLOW THE USER
;TO SEND MESSAGES TO OTHER JOBS OF HIS.

;THE FOLLOWING MACRO DEFINES ALL THE FUNCTIONS.  THERE ARE FOUR
;ARGUMENTS FOR THE DEFINITION OF THE MACRO:
;
;	MNEMONIC, PRIORITY, LENGTH, COMMAND
;
;"MNEMONIC" IS THE 3-LETTER COMBINATION UNIQUE TO THIS FUNCTION WHICH
;   IDENTIFIES THAT FUNCTION.
;"PRIORITY" DETERMINES THE ORDER THE FUNCTIONS ARE EXECUTED IN, LOWER
;   LETTERED FUNCTIONS FIRST.  IF 2 FUNCTIONS HAVE THE SAME PRIORITY, THEN
;   THE ORDER IS UNIMPORTANT.  IF TWO OR MORE LETTERS APPEAR, THEN THIS
;   FUNCTION WILL BE CALLED ONCE FOR EACH PRIORITY.
;"LENGTH" IS THE LENGTH OF THE ARGUMENT BLOCK IN THE TMPCOR REPRESENTATION
;   INCLUDING THE FUNCTION CODE ITSELF.  ZERO MEANS THE LENGTH ISN'T FIXED,
;   AND THAT THE LENGTH OF THE BLOCK WILL BE COMPUTED BY A SUBROUTINE.
;"COMMAND" IF PRESENT, IS THE USER-TYPED COMMAND AVAILABLE FROM THE TTY.
;   IF NOT PRESENT, THERE IS NO COMMAND FOR THIS FUNCTION.
;
;*** WARNING:  ADD NEW FUNCTIONS ONLY AT THE END OF THE LIST, AND REPLACE
;ANY FUNCTION TO BE REMOVED WITH A NO-OP FUNCTION, BECAUSE THE ORDER OF
;THE DEFINITIONS IS USED TO GENERATE THE FUNCTION CODES.
