> On a Dec-20, you have a huge number of strange instructions, including :

Actually it's stranger than you said.  Instructions include:

SKIP	Don't skip
SKIPA	Always skip
JUMP	Don't jump
JUMPA	Always jump

On the IBM 360/370 series, the branch instrction has a condition mask for
the various states of the condition code.  If you set all of the mask bits,
it branches on any possible set of condition bits, i.e. branch if true.  If
you set none of the mask bits, it's the no-op instruction, i.e. branch if
false.

This has nothing to do with net.lang.c, followups to net.arch or perhaps
net.games.trivia.
