CASE vs. IF

I just re-read these sections. Wondering if anyone would like to offer an apples and oranges example for this one too?

I get the feeling that the two commands are pretty much identical. Would one (CASE?) be better suited to dealing with numbers versus the other? Is there something that fundementally sets them apart from one another?

    In my eyes IF is suited for 1 to 3 possible matches where case is suitible for more possibilitys like ranges and lists

    the primary difference is readability

    Who says you have to have knowledge to use it?

    For multiple cases and certainly for ranges, CASE is more efficient than IF/ELSEIF/ELSE. CASE executes faster, too, for multiple checks. You can·experiment with either·construct and then check the code size difference. Use F9 to compile and then·move the cursor into your PUB/PRI to see how many Spin bytes it compiled to. This will be shown in the status bar at the bottom of the window.
