> Normally you are right: bit manipulation is easiest with SET, eg my color display driver is full of SET manipulations. 

Inspired by Chris, I looked up NW papers and I found some SET advocacy there:

www.inf.ethz.ch/personal/wirth/Oberon/index.html  --> SET: A neglected data type and its compilation for the ARM

Unfortunately, the conversion between the SET and INTEGER is not covered in that note. The discussion of SYSTEM.VAL versus nonexistent BITS is still not resolved in that paper.
