.me2

 LDA MCH                \ Fetch the token number of the current message into A

 JSR MESS               \ Call MESS to print the token, which will remove it
                        \ from the screen as printing uses EOR logic

 LDA #0                 \ Set the delay in DLY to 0, so any new in-flight
 STA DLY                \ messages will be shown instantly

 JMP me3                \ Jump back into the main spawning loop at TT100
