 JSR TT27               \ Call TT27 to print the text token in A

 LSR de                 \ If bits 1-7 of variable de are clear, return from the
 BEQ out                \ subroutine (as out contains an RTS). This means that
                        \ " DESTROYED" is never shown, even if bit 0 of de is
                        \ set, which makes sense as we are docked

 LDA #253               \ Print recursive token 93 (" DESTROYED") and return
 JMP TT27               \ from the subroutine using a tail call
