;COPY INTO YOUR TERMINAL-DEPENDENT MODULE, OR USE AS GUIDES

;CONTAINS PAIRS OF ROUTINES: THE FIRST POSITIONS TO ROW (RW) COLUMN (CM)
;THE SECOND POSITIONS TO THE START OF LINE (T4)
;(RW, CM, AND T4 ARE ACCUMULATORS)
;THE ROUTINES ALL DO A "POPJ P," WHEN DONE

;SUBROUTINES THAT MAY BE CALLED BY THESE ROUTINES:

;MOVE  T1,NUMBER       ;PUTNUM - OUTPUT DECIMAL NUMBER IN T1
;PUSHJ P,PUTNUM

;MOVEI T1,[ASCIZ /STRING/] ;PUTSTG - OUTPUT STRING POINTED TO BY T1
;PUSHJ P,PUTSTG

;MOVE  T1,[ASCII /CHARS/] ;PUTSQ1 - OUTPUT UP TO 5 CHARACTERS IN 1
;PUSHJ P,PUTSQ1

;MOVEI T1,"X"    ;OUTPUT A SINGLE CHARACTER
;IDPB  T1,TY

;PUSHJ P,PUTTYP  ;OUTPUT THE TYPE BUFFER TO THE TERMINAL
                 ;(NORMALLY THIS WILL BE DONE AFTER THESE ROUTINES RETURN)
