The first character in a string is always at index 1 because of this. Strings are `Packed Array[0..255] of Char` See https://www.pascal-programming.info/lesson10.php

Pascal has both. Static arrays in Pascal can have arbitrary indexes with mixed data types:

Examples:

- var MyArray: array [1..100] of Char;

- packed array[Boolean, 1..10, TShoeSize] of Integer;

Dynamic arrays are indexed from zero.
