TP, Thanks for the reply.  With trying multiple things and reading more on VB Scripting I was able to figure it out.  It works the way I want it to now.  In a nutshell here is what I was trying to do.  I made a label saying Tool Up Position, next to that I have a DRO.  What I am trying to see on the screen is the Tool Up Position for when the ATC carousel can slide into the extend area for the tool change.  At that point the Z axis will come down and pickup the tool, that being the Tool Down Position for the Z.  I added a button next to the DRO that says (Tool Up Position).  I can now click on the button and the DRO will indicate the Tool Up Position.  I am ready to take it a step further and make the button move the Zaxis upto that Tool Up Position so that I could do a manual tool change for when I implement my touch screen.  I am really making my ATC screen look similar to one I found on the net that I like with a few mods of my own.
I hope it all works like I have planned.
Thanks,
Jeff
