| This may seem like more work, but in my experience you write a few of these

  I agree with your thought, although for portable transfer I usually do
LSB first (not because of any preference) just for the loop. Since I
work with 36 and 64 bit machines, I always add a sign extend on the
read.

  At one time I was operating a PC (original IBM) with a unique
coprocessor Cray2 on an ethernet link. The C2 calculated data and passed
it in 32 bit RLE format to a BASIC program which used calls to write the
display. Amazing what you can do to get a demo up FAST.
