Is there way to select pulleys within a brain?

Hood wrote me a Brain and a macro to automatically select pulleys .  I am about 2 weeks ago from setting up my machine and trying it out.  I have a Bridgeport mill with a backgear and VFD.  the back gear has a prox switch made when in high and off when in Lo.  basically the macro gets the S command and figures out which pulley to use and pops up a message for me to change gears, when the prox is in the right state I can press OK and the program continues.  I'll let you know how it works and post it on the forum if successfull. 

Hood's brain seems to work. 

I can't seem to upload teh macro.  E mail me and I will attach it for you
