在悉尼，移动端的字符串仍然为零吗？

In Sydney does string still zero based in mobile?

当我阅读文档时：http://docwiki.embarcadero.com/RADStudio/Sydney/en/Migrating_Delphi_Code_to_Mobile_from_Desktop 说移动字符串是基于 0 的，但我听说情况不再如此，所以文档不准确吗？

"..so is the doc inaccurate ?"

是的，您正在阅读的文档没有更新最新信息。

参见Zero-based strings：

Compilers (desktop and mobile) have as predefined {$ZEROBASEDSTRINGS OFF} indicating the use 1-based string indexes.

Note: Previous to Delphi 10.4 the mobile compilers used by default 0-based indexing for strings.

您仍然可以通过设置 {$ZEROBASEDSTRINGS ON}

使用从零开始的字符串

也来自文档：

In general terms, string indexing is now uniform across platforms and uses 1-based index model.

Notice however that:

Delphi string type helpers (TStringHelper) remain 0-based.

All Delphi global flat functions are 1-based.
