 JMP DOENTRY            \ Decrypt the main docked code and dock at the station

 JMP DOBEGIN            \ Decrypt the main docked code and start a new game

 JMP CHPR               \ WRCHV is set to point here by elite-loader3.asm

 EQUW IRQ1              \ IRQ1V is set to point here by elite-loader3.asm

 JMP BRBR1              \ BRKV is set to point here by elite-loader3.asm

 BRKV = P% - 2          \ The address of the destination address in the above
                        \ JMP BRBR1 instruction. This ensures that any code that
                        \ updates BRKV will update this instruction instead of
                        \ the actual vector

 PRINT "S% workspace (docked) from ", ~S%, "to ", ~P%-1, "inclusive"
