I prefer switch/case statements when there are many options a
script has
to deal with. I'll admit though that there is little difference
between
switch/case and if/then constructs when the choices are
straightforward.

The above construction is easier for me to read and executes faster
in a
script.
Yes, as a programmer who (years ago) used to program at a low level
(including some compilers), I feel that there's at least the
possibility that a long case statement can be compiled in such a way
as to run faster than a lot of 'if' statements. I sense some kind of
lookup table being used. Of course this may not be the case at all,
but at least it's faster **in principle**. I admit this is a very
geeky way of looking at it.
OTOH I agree with all the other people who said a case (switch)
statement seems clearer than the 'if' construction for long multiple-
choice logic. I am not at all nostalgic for my low-level days and
feel thankful every day for the clarity and power of xTalks.
