|Turbo Pascal and "C" have native bit-shifting operations, but not

|to read some opinions on this question.

Yes, but if you're going to compare, Turbo Pascal is not standard
Pascal.

A good question though is: what do people use bit shifting for in
C and how would one write the equivalent in M-2? I know I use bit
shifting to (1) make bitmasks, which M-2 can do with BITSETs and
(2) (not so much now) multiply and divide, which shouldn't be
a BITSET operation anyhow. So what can BITSETs not do?
