I nearly cried when tmoran@bix.com said:
>>find "X mod 16#10000#" *more* clear than "X and 16#FFFF#"
>but not easily generalizable to "X and 16#FF7F#"
Quite true, which is why one should choose the appropriate tool
for whatever one happens to be doing: bit extraction uses
Boolean operators, modular arithmetic doesn't. There you go.
The difference between extracting the bottom eight bits and
doing arithmetic modulo 256 can be subtle of course.
