I learnt earlier OberonV5 is little endian.
Toying with bit reversal, and printing in binary, I further discovered
that bit numbering is MSB 0, correct?
Example, printing 128 in binary gives,
Also when shifting bits in display buffer,
shifting bits left = moves screen bits visually to right
shifting bits right = moves screen bits visually to left, correct?
This may explain why bit reversal, and endian conversion is needed in
`Screen.Mod' to produce bitmaps for the outside world.
Little endian + MSB 0 simplifies h/w design, correct?
