Chr(n)

Returns the character as a text that corresponds to the numerical ASCII code n (a number between 0 and 255). Chr and Asc are inverses of each other, for example:

Chr(65) → ‘A’, Asc('A') → 65

Chr is useful for creating characters that cannot easily be typed, such as tab, which is Chr(9) and new line or carriage return (CR), which is Chr(13). For example, if you read in a text file, x, you can use SplitText(x, Chr(13)) to split the file up at each new line character into an array of lines.

-The mapping for characters from 128 to 255 is subject to your system's language/region-specific character map.  Analytica 4.0 has adopted a Windows mapping, while Analytica 3.1 and earlier used a Macintosh standard mapping, see [[Asc]].
