T3=3	;startiON SYt  T1  and working toward T5.
T4=4	;In general T0 will contain an  item  for
T5=5	;input  or  output  or  the  result  of a

G3=10	;another routine is  assured  the  GLOBAL
G4=11	;AC's  will remain unchanged, unless data
	;is to be passed as  arguments.   Passing
	;of  arguments must be clearly defined by
	;documentation in the calling and  called
	;routines.
;PERMANENT AC
P1=12	;P1 IS USED AS AN INTERNAL JSP AC.
P2=13	;AC P2 contain a pointer to  the  encoded
	;format  statement  in the right half and
