Pete,

        The byte ordering used on Intel processors is the same as the VAX, I
believe. It's a simple case of little-endian versus big-endian. Thus, the value
$ABCD would be seen in memory as CDAB. I assume that in your examples, you used
4-byte numbers. (Otherwise you'd be implying that the VAX swapped the order of
the two nibbles within a byte.) On Intel processors, the most common data types
and their values are stored as follows:

        int     CDAB            ($ABCD)
        long    CDAB2301        ($0123ABDC)
        far ptr CDAB:2301       ($0123:ABCD)

Of course the colon isn't stored in memory, but it helps to clarify a far
pointer consisting of a segment:offset. The values in parantheses are the
actual values you'd feed to the assembler. Oops, that should be ($0123ABCD) for
the long - I accidentally swapped C and D.
