!

This simple command tell the compiler to stop accepting new commands on the track where it is used. It will act almost as if the rest of the track is commented out; even errors related to use of commands on the track after this command won't be found — however, it will still catch invalid commands. It is very useful when doing tests: you don't need to comment all the rest of the track manually.

Example:

A v10
; Notice that all after ! is ignored, even invalid use of commands.
A L c e g ! >c d e g &&& 
A garbage^32 t12 & ^12
