 There are three of these. The only difference is the hardware address and 
the LAND number.
 This is the X  axis. The Y and Z are FF61 and FF62 respectivly. The LAND 
numbers for all three are 1, 2 and 4.
 Of course, there is the DIM statement to define x at the beginning of the 
routine and defining the value of stepper(x) which is 1,2,4,8


 I think I streamlined this as much as can be done with my knowledge of B09.

WHILE LAND(PEEK($FF64),1)=1 DO
x=x+1
IF x>4 THEN x=1 \ ENDIF
POKE $FF60,stepper(x)
ENDWHILE


  There are roughly 6400 steps per inch for the home of the axis in this 
mode. The machine is six by six inches on the X and Y axis and about 3 
inches on the Z axis.
 When I did the test on speed, the X was at 4.9 inches, Y was at 2 inches 
and Z was at 3.4 inches.
 At 6400 steps/inch, and all three axis having to step all the way back to 
home, this is a LOT of steps so, I'm not disappointed with the operation.
 I was just curious about packed and non packed B09 procedures.
  When actually machining, I use half steps which doubles the steps/inch.. 
At 12800 steps/inch, this takes some time. Multiply that times the three 
axis... well, go fugure.

 I do not run any other applications or utilities while dong this machining. 
Give the coco a break! It's plenty busy doing just this!
