CharNOT()

Binary NOTs the ASCII codes of characters in two strings.

Syntax

CharNOT( <cString> ) --> cResult

Arguments

<cString1> and <cString2>

These are two character strings whose ASCII codes are NOTed in the result string.

Return

The function returns a string by NOTing the ASCII codes of the individual characters of both input strings.

Description

The function operates until all characters of <cString1> are processed. It distinguishes the following situations:

1)	Len( <cString1> ) == Len( <cString2> )

When both input strings are of the same length, the ASCII code of each character in <cString2> is ANDed with the ASCII code of the corresponding character in <cString1>.

2)	Len( <cString1> ) > Len( <cString2> )

When the last character of <cString2> is reached, the function starts over with the first character of <cString2>, until the last character of <cString1> is processed.

3)	Len( <cString1> ) < Len( <cString2> )

The function returns when the last character of <cString1> is processed.
