Characters¶
The atoms of a string are ASCII characters.
Extraction from String¶
The first character of a string can be extracted:
var ch : char = char "Hello";
This sets ch to the letter H. If the string is empty, the char becomes NUL.
Ordinal Value¶
The code point of the character, from 0 to 255, as an int:
var ch = char "Hello"; // H
var j = ch.ord; // 72
Construction from Ordinal Value¶
Finds the n’th character in the ASCII character set.
var ch = char 72; // H
