You used to be able to order the manual from HP. God knows whether
they provide that service now. (And they screwed up the copying of
my HP-97 manual.) I have one extra Xerox copy of the manual from HP
(I got it, then I got an original manual.)
LJ is left justify. Given a word with leading 0s, it removes them;
it also returns the number of leading 0s. Before --
x
n 0 bits, 1 bit, other stuff
After --
x y
n 1 bit, other stuff
A few other exotic operations include counting 1 bits and generating
masks. Let me know if you have more questions.
