At one point fpGUI switched all list type components to be 1-based. This
caused such a lot of issues that I very quickly switched it back to
0-based. Why? Because even though my components were 1-based, the FPC lists
where 0-based. So I had to very carefully keep track of which one uses what
and often made mistakes. I personally hate 0-based counting because no
human counts 0, 1, 2 etc.. so why must computers? But because 0-based is so
standardized in programming languages, it's just easier to follow the crowd
than fight them. :-)
