With a conditional structure you would write:
if x < 100 or x > 500 or (x > 200 and x < 400) then
<statements>
else
<other statements>
end if
The first formulation seems much more clear to me :-)
To me no. The if statement seems all too clear. I think this
greatly depends on what past experiences a programmer may have had.
I spent years programming in Visual DialogScript on Windows, and
there were no switch/case in the syntax (It's an odd syntax in the
first place). The above would look like this:
If @not(@greater(%x,100))@greater(%x,500)@both(@greater(%x,200),@not
(@greater(%x,400)))
<statements>
else
<statements>
end
So you can see how one could become rather used to a certain flow or
way of things. It becomes second nature. I haven't programmed in
Visual DialogScript since last summer and still instinctively I was
able to toss together the if structure there. And of course, it
carries over when moving to another language. That and one other
thing, is that you can always count on another language having "IF/
ELSE/END" in it's syntax, so it's kind of a universal attribute for
programming languages.
Not that the switch/case isn't more logical or vice versa.
