Introduction to Delphi strings and Delphi strings

I used to program Windows under Delphi and used to use strings. At that time, the string starts from serial number 1, not 0.

Currently, Delphi supports multiple platforms, and the situation may change.

1. In VCL mode (Windows only), the string is the same as before. It still starts from 1; the previous string functions such as Copy and Pos can still be used.

2. In FireMonkey mode, the string starts from 0 regardless of whether the compiled target platform is Windows or not. In this case, we want to perform operations such as Copy and Pos. Instead of using previous functions, we 'd better use the string's Helper function. For example, a string S: string can be defined. You can use S. Remove.
