  1. Où es-tu Mr Wirth ?
     
    ```html debut equ 1000h
    fin equ 1010h
    ld ab,debut
    ld hl,fin
    ld bc,fin-debut+1
    ldir

    you need to adapt this to a modern proc... because this one is limited to 64k ```

      Here is the solution


      LDX #$ 10000 START
      LDY #$ 20000
      LDA 0,X+
      STA 0,Y+
      CMPX #$ 10100
      BLS (-7)
      SWI END


      Note: the addresses need to be in hexadecimal.
