About API SCI_INDICATORSTART

[minico]

Hi Neil,
I have some confusion about the 2nd parameter of message SCI_INDICATORSTART.
For example, If there is an indicator 10 at position 100,
When I run Call(SCI_INDICATORSTART, 10, 0), it always returns 0;
but if I run Call(SCI_INDICATORSTART, 10, 100), it will return 100.

By scintilla document, the 2nd parameter is the position start to search
the specified indicator.
so I think when I run Call(SCI_INDICATORSTART, 10, 0), it should returns
100; right?

It may be better to think of indicators not as something that exist at particular positions but as something that has a value at every position. So you have a situation in which indicator 10 has value 0 from position 0 to 100 and value 1 after that. The SCI_INDICATORSTART API provides a way to find the position where a value started.
