Remarks
When to use CHR( )
Use the CHR( ) function to return the character associated with any ASCII code, including those characters that cannot be entered directly from a keyboard or displayed on screen. With CHR( ), you can search fields or records for the existence of these specific characters.
Referencing NUL
Referencing the ASCII NUL (null) character, CHR(0), may produce unpredictable results because it is used by Analytics as a text qualifier, and should be avoided if possible.
