BLABLABLA@DODGIT.COM Your'e right, Mister. That's why the extracted application is like 9 MB in size. A bit oversized for this task.
I have a BMI Example in a cocoa book. It was very useful to see how connections are made (Interface Builder, a window with 3 text-fields and one button :), but the BMI-Task himself is rather boring. (Version 1.0)
NAOH This app seems like a developers first attempt at using RealBASIC.
It's not bad, but it is basic.
For future versions, I'd suggest adding the ability to use metric or even mixed measurements. (Metric height and Imperial/US weight, for instance.) (Version 1.0)
