OSBYTE &BA
OSBYTE &BA (186) - Read/Write ROM active on last BRK
The last ROM which caused a BRK is recorded so that the current language ROM can extract the error text (using OSReadROM) if the error text resided in ROM. Since the language ROM would cause the error message to be paged out they should make a RAM copy of the message instead.
