    If you really want to hack an initialisation to a fixed memory
    location, you could compile a file which might say:

    #pragma SRC
unsigned int xdata variable = 0x1234;
    then look up the ?C_INITSEG-Part of the generated
    Src-file and copy this into a separate assembly - module,
    adding:
    EXTRN XDATA variable
    I've once tried this and it worked fine, but I never tried it
    with fixed memory locations.
