Is it possible?  The code below drops out after the first run of the internal subroutine.

(#1001 = X Axis)
(#1002 = A Axis)
(#1003 = A Axis Increment)

#1001=0
#1002=22.5
#1003=22.5


M98 P1002 L9
  O1002

    M98 P1001 L8
       O1001
       g0 x#1001 A#1003
       G73 z-.04 r.0 q.02 f3
       #1002=[#1003+45]
    M99


  #1001=[#1001+.333]
  #1003=[#1003+20]
M99

Should work like this

Graham.

(#1002 = A Axis)

Graham you won! 

This program drills 8 holes equally spaced on a diameter and then increments over .333 in the X and offsets the holes 20 degrees 9 times.

Although my offer of one million dollars has expired let me offer a hearty "THANK YOU" for your expeditious response and expertise in helping me reach my goals!  Now back to work!

Had a small change to the program to make it work properly.  Thanks again Graham.

I plant seeds and hope they flourish.

Graham.
