Oh no ! ;-)
I have only recently got round to using switch statements, to improve
code legibility. In my current/first embedded project, I happen to have
a very long (25 cases, 160 lines long) switch statement.. I dread to
think what it would like if I had to replace it (what else with ?) with
nested if's !
How readable would that be... not to mention that with indentation, 25
levels of nesting would mean the last case would be 3 meters on the far
right... ;-)

Any coding tips to make all this look about readable by human
beings ?! ;-/

Vince, catastrophed...
