Yes, of course. You can enter any valid command by MDI. But, you can also
do it on screen with just a couple of mouse clicks and keystrokes. Much
faster
than MDI. The later versions of EMC clear the G92 offset at the end of
the program. But, the end of program does NOT clear the offset entered
through the mouse right click.

M06 really has no meaning unless you have a tool changer. It is the G43
command
that selects tool length offsets.
