Learning how to Program the Amiga

Here's a link to Hello world for 68k Amiga:

Here is some learning guides:

I think you should try some examples and see which one feels right to you. Once you get use to accessing the hardware you could probably switch over to C later.

Here's a link to Hello world for 68k Amiga:

And here's the fixed version of the same example:

Code: [Select]

       include lvo/exec_lib.i
        include lvo/dos_lib.i

        ; open DOS library
        movea.l  4.w,a6
        lea      dosname(pc),a1
        moveq    #36,d0
        jsr      _LVOOpenLibrary(a6)
        tst.l    d0
        beq.b    .nodos
        movea.l  d0,a6

        ; actual print string
        lea      hellostr(pc),a0
        move.l   a0,d1
        jsr      _LVOPutStr(a6)

        ; close DOS library
        movea.l  a6,a1
        movea.l  4.w,a6
        jsr      _LVOCloseLibrary(a6)
        moveq    #0,d0
        rts

.nodos:
        moveq    #20,d0
        rts

dosname     dc.b 'dos.library',0
hellostr    dc.b 'Hello, world!',0


Changes:
- Properly test for OpenLibrary failure. No longer crashes when run on KS 1.3.
- Set return code properly.
