Wel, yes, it *is* the current language.

"In" the MOS?

"Pretend to be the MOS"? What do you mean by this? Pretend to
implement the VDU and keyboard drivers? All it's doing it letting
the user enter * commands, which is a lot better that issuing an
error and then hanging.
 
Standard code for a language that can't find the resources it
depends on. Loop with a * prompt.
