Types ¶ RUNE (Alias)

RUNE (ALIAS) ¶ TYPE RUNE : DINT(0..c_diMaxRune) The term rune appears in the libraries and source code, and means exactly the same as “unicode code point”, with one interesting addition. This library defines the word rune as an alias for the type DINT , so programs can be clear when an integer value represents a code point. Moreover, what you might think of as a character constant is called a rune constant. The type and value of the expression WSTRING#"⌘" is a rune with the integer value DINT#16#2318 .
