On the BBC micro they’re normally used to call a break handler.
So basically memory is as follows:-
BRK (first)
Fault number
Fault Message
Null terminator
I refer you to page 464 of the BBC micro user guide which describes how you use it. There is a potential gotcha though as the MOS (machine operating system) uses a vector at 0x202 for this which may have been appropriated.
