 No, 'N' and 'M' are the maximum counts you desire; the '1's are the
 starting value.  For example:

  20 10 DO  LOOP

 Counts from 10  19.  Starting with 1 gives you the familiar 1 to n
 count.  The count index is 'I'.  Within the loop, 'I' puts the present
 count value on the top of the stack.  For nested loops, as in your
 question, 'J' returns the count value (index) of the next outer loop. 
 You don't have to declare 'I' or 'J'.
