Utility routines: BRBR

       Name: BRBR                                                    [Show more]
       Type: Subroutine
   Category: Utility routines
    Summary: The standard BRKV handler for the game
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * BRKBK calls BRBR


 This routine is used to display error messages, before restarting the game.
 When called, it makes a beep and prints the system error message in the block
 pointed to by (&FD &FE), which is where the MOS will put any system errors. It
 then waits for a key press and restarts the game.

 BRKV is set to this routine in the loader, when the docked code is loaded, and
 at the end of the SVE routine after the disc access menu has been processed.
 In other words, this is the standard BRKV handler for the game, and it's
 swapped out to MEBRK for disc access operations only.

 When it is the BRKV handler, the routine can be triggered using a BRK
 instruction. The main differences between this routine and the MEBRK handler
 that is used during disc access operations are that this routine restarts the
 game rather than returning to the disc access menu, and this handler
 decrements the brkd counter.


.BRBR

 DEC brkd               \ Decrement the brkd counter

 BNE BR1                \ If the brkd counter is non-zero, jump to BR1 to
                        \ restart the game

 JSR RES2               \ Reset a number of flight variables and workspaces
                        \ and fall through into the entry code for the game
                        \ to restart from the title screen
