XOR

Returns a string that is the logical XOR of the argument strings. There must be two or more arguments and they must be character strings.

Example:

Assume column L1 has a value of X'E1E1', column L2 has a value of X'F0F000', and column L3 has a value of '0000000F'.

  XOR(L1,L2,L3)

Returns the value X'1111404F'. In this case, the shorter results are padded with blanks (X'40').
