OS_Bye, Exit application

Register parameters

RST 20H, DEFB $21

IN:
     A = system error code to display standard error box message
     A = 0, no error message after exit

OUT:
     -

Notes

This is the call which the application must make to terminate itself; in particular in the error handler when responding to a <>KILL request. Note that this call does NOT automatically close files and deallocate memory - the application must do this before making the call. Register changes are not fixed, as the code previously executing is not re-entered.
