MACRO-11 help - test-drb@ccmp.vtda.org

Sigh.  I really should read what I've written, before I post it.  Being in
a
hurry is no good excuse.

I missed out a whole column (the destination address) in the JSRs!  And
forgot
to alter the addresses to allow for the different instruction lengths :-(

  Now if he wanted to write it using a subroutine, and
he used the simple
 method: 
It should be something like:

       7 001000 012701  000110                  MOV     #'H', R1
       8 001004 004537  001100                  JSR     R5, @#PUT
       9 001010 012701  000064                  MOV     #'4', R1
      10 001014 004537  001100                  JSR     R5, @#PUT
      11 001020 012701  000130                  MOV     #'X', R1
      12 001024 004537  001100                  JSR     R5, @#PUT

      36 001104 100375  			BPL	PUT
      37 001106 010137  177566  		MOV	R1, @#XBUF
      38 001112 000205  			RTS	R5

  However, if it were written using relative addressing,
ie 
       8 001004 004567  000070                  JSR     R5, PUT
       9 001010 012701  000064                  MOV     #'4', R1
      10 001014 004567  000060                  JSR     R5, PUT
			  :
      35 001100 105767  177564        PUT:	TSTB	@#XSR

Apologies for any confusion.
