View source for Text functions


__TOC__
These functions work with '''[[Operators#Text values|text values]]''' (sometimes known as strings), available in the built-in Text library.

==Asc(t)==
Returns the ASCII code (a number between 0 and 255) of the first character in text value t. This is
occasionally useful, for example to understand the alphabetic ordering of text values.

==Chr(n)==
Returns the character corresponding to the numeric ASCII code '''n''' (a number between 0 and
255). '''Chr()''' and '''Asc()''' are inverses of each other, for example:
 Chr(65) &rarr; 'A', Asc(Chr(65)) 􀃆 65
 Asc('A') &rarr; 65, Chr(Asc('A')) 􀃆 'A'

<code>Chr()</code> is useful for creating characters that cannot easily be typed, such as ''Tab'', which is <code>Chr(9)</code> and ''carriage return (CR)'', which is <code>Chr(13)</code>. For example, if you read in a text file, <code>x</code>, you can use
<code>SplitText(x, Chr(13))</code> to generate an array of lines from a multiline text file.
