[some boring C-code deleted]   :-)

Ok, assembler strikes back with this: (56 codesize, 92 executable)

OpenLib=-408
Output=-60
Write=-48

  move.l 4.w,a6
  lea    dos(pc),a1
  jsr    OpenLib(a6)
  move.l d0,a6
  jsr    Output(a6)
  move.l d0,d1
  lea    hello(pc),a0
  move.l a0,d2
  moveq  #12,d3
  jmp    write(a6)

dos:   dc 'dos.library',0
hello: dc 'Hello World',10
