| + | ======Synopsis:====== | ||
| + | $[[ascii]](<character list>) | ||
| + | |||
| + | ======Technical:====== | ||
| + | The [[ascii]] function converts a sequence of characters into a word list | ||
| + | of codepoints. Because EPIC only supports latin-1 at this time, all of | ||
| + | the codepoints are 0 to 255 (strictly 1 byte per codepoint). If in the | ||
| + | future epic supports UTF8 or something like that, codepoints greater than | ||
| + | 255 might be returned. | ||
| + | |||
| + | You can use the [[chr]] function to convert a word list of codepoints into | ||
| + | a sequence of characters. The same caveats about encoding applies. | ||
| + | |||
| + | By definition, the [[ascii]] and [[chr]] functions are symmetrically | ||
| + | reverse operations of each other. | ||
| + | |||
| + | ======Examples:====== | ||
| + | <file> | ||
| + | /* assume iso8859-1 character set */ | ||
| + | $ascii(abcABC) returns "97 98 99 65 66 67" | ||
| + | $chr($ascii(abcABC)) returns "abcABC" | ||
| + | </file> | ||
| + | |||
| + | ======Other Notes:====== | ||
| + | Some characters with the high bit set will return negative numeric | ||
| + | values from $__ascii__(). Add 256 to this negative value to get its | ||
| + | positive equivalent. The $__chr__() function will accept either. | ||
