Well, as I stated in a message to George Emery, the problem is not only
the shifting, but also the possiblity of overflow.

Furthermore, putting all my routines in a single fixed point module
enable me to play a bit with different representations of fixed
point numbers. This enables me to get optimum range and accuracy in
my particular program. (I hope. B-))

Best regards,
Ben
