WebJul 8, 2015 · XOR operation between two bits returns 1 if one and only one of the two bits is 1; 0 otherwise. Another way to explain is that that it returns 1 if the two bits are different; 0 otherwise. XOR operation between two binary numbers of same length works likewise on a bit-by-bit basis. XOR two numbers you get a number with bits set to 1 where ... WebCreate a Binary Table. This is a rather esoteric coding technique for creating a sequential 256 byte table of the character set using a single instruction. The technique uses the addressing constant (ADCON) function of mainframe assembler. Let's take a look at how the 256AL1 (*-TABLE) creates a 256 byte EBCDIC table.
