String index V.S. Array index in Delphi

I'm used to develop code in C, however someday I meet the need which the code was written in Delphi.

The amazing fact in Delphi is the index on array and string differs ! This is really shock, it shocked me almost put hands in my mouth. 嚇得我吃手手...

In Delphi, Strings are 1-indexed, but arrays are 0-indexed.

也就是說如果有一個變數被設為 String 例如說 S:=Foo.Bar().AsString;
如果要存取 S 的第一個字元要使用 S[1] 才會是正確的字元。

If S is assigned as a string variable, the first character would be S[1] not S[0];
