No problem, Dave, I'll be out for a while, too.
Now that I think about it, I probably could put my script in an *.m1s file, put it where the other scripts are, C:\Mach3\ScreenSetMacros\MachStdMill.set\scripts, call it whatever dot m1s, then edit the button script to call that. I see how it works now, I think. I'll wait for your official response, however!!
Thanks
Tom
