Probably beating a dead horse by now - but my favourite analogy for this
is ....
Think of the code within the switch .... end switch delimiters as a
freeway (motorway)
the case statements are possible ENTRY points (on-ramps):
if you haven't already entered, the case is evaluated and you
MAY then enter the freeway
the break statements are EXIT points (off-ramps):
if you run into a break statement, you do exit the switch block.
Note that the case statements are NOT off-ramps; they do not cause you
to leave if you're already on the freeway. But, most of the time, an
on-ramp will be preceded by an off-ramp.
(Sorry if that analogy is getting stretched, esp. if you live in an area
where all the junctions are clover-leafs, and the off-ramps come after
the on-ramps :-)
