+ | ======Synopsis:====== | ||
+ | $[[chr]](<list of codepoints>) | ||
+ | |||
+ | ======Technical:====== | ||
+ | The [[chr]] function converts a word list of codepoints into a sequence of | ||
+ | characters. Because EPIC only supports latin-1 at this time, only the | ||
+ | codepoints 0 to 255 provide defined behavior. Other codepoints will yield | ||
+ | one character per codepoint, but the character is undefined. | ||
+ | |||
+ | For backwards compatability, [[chr]] accepts the values (-1 to -128) to be | ||
+ | equivalent to (128 to 255). This is not guaranteed in the future. | ||
+ | |||
+ | In the future, if epic supports utf8 or the like, codepoints outside of the | ||
+ | range 0 to 255 would be supported. | ||
+ | |||
+ | ======Examples:====== | ||
+ | <file> | ||
+ | /* assume iso8859-1 character set */ | ||
+ | $chr(3) return a ^C (color change attribute) | ||
+ | $chr($ascii(abcABC)) returns "abcABC" | ||
+ | </file> | ||
