CharXOR()

Binary XORs the ASCII codes of characters in two strings.

Syntax

CharXOR( <cString1>, <cString2> ) --> cResult

Arguments

<cString1> and <cString2>

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

Return

The function returns a string by XORing 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> )!EF

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

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

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> )!EF

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

Note:  CharXOR() exists for compatibility reasons. It is superseeded by xHarbour's binary XOR operator.
