G-Code Question: Tool Change without Operator Confirmation (lathe) (Resolved)

I'm writing some g-code and can't figure out how to change tools while suppressing the prompt that requires the operator to verify the tool and press cycle start to continue. This is on a gang lathe, so tool changes are automatic but there is no ATC. The command I am using is simply:
N0010 T0101
Your help is appreciated!

The T code is a 4-digit number. The first two digits are the tool number (tool location); and the second two digits are the offsets to use.
The control will "run a tool change" (e.g. prompt the operator) any time the first two digits change. So the simplest way to run without tool-change prompts is to change offsets, but never change tool numbers. E.g.:
or just:
which is equivalent to:
Alternately, you can add a custom tool-change macro file which does nothing. E.g. create a file named "cnctch.mac" in the c:\cnct directory, and leave it empty, or just put in a comment:
cnctch.mac:

It took me a few days to get the chance to try this out, but it worked great. I used your suggestion of modifying the cnctch.mac file.
Thank you Sir!
