Bit-wise exclusive OR two strings

Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $StrXor function is BitXorString.

This function performs a bit-wise exclusive OR of two strings.

The $StrXor function accepts three arguments and returns a string result that is the bit-wise exclusive OR of the first two arguments, the shorter being padded with as many copies of the third argument as are required to make the string lengths equal.

Syntax

%STR = $StrXor(string1, string2, [pad])

Syntax terms

%str The bit-wise AND of string1 and string2.
string1 An arbitrary string.
string2 Another arbitrary string.
pad An arbitrary string that is appended to the shorter of the first two strings and replicated as many times as required to make the strings of equal length. If this value is not specified or is null, it defaults to a single null byte (X'00').

Examples

  1. This code fragment would set %junk to X'746112445566':

    %X = $X2C('112233445566') %Y = $X2C('654321') %junk = $StrXor(%X, %Y)

  2. These statements would set %junk to X'DDEEFF8899AA':

    %X = $X2C('112233445566') %junk = $StrXor(%X, , $X2C('CC'))

  3. This code fragment would set %junk to X'0000CC44AA66':

    %X = $X2C('112233445566') %Y = $X2C('1122') %Z = $X2C('FF00') %junk = $StrXor(%X, %Y, %Z)
