I remember IF constructs from BASIC and PASCAL, but no switch statements
(somebody correct me if I'm wrong). But what I'm wondering is how in the
world did you do conditional checking if there were no switches, and you
don't use IF's? Did you not code error handling, different cases based on
user input, status of a data stream, etc in all the years prior to
something like switch being introduced???

Ye gods -- I'm getting old. I had to look this up.
Yup - Pascal has
case operator of
.. statements ...
otherwise
.. statement
end;
And you can group cases.
Forgotten all that - had to look it up.
What I think happens is that we are merrily noodling along in our code,
and a condition rears its head. Simple - if .. else. Then things get a bit
more complicated, and so we end up with nested if .. elseif .. else constructs.
Personally I like the clarity of switch, but don't use it often because I
generally try to avoid messy nests of conditions.
