<p>An apparatus for utilizing a logical compare instruction is disclosed. The apparatus develops a data field descriptor associated with and describing the attributes of each of the operands of the compare instruction. If the operands have different formats, when matching the contents of a first operand to the contents of a second operand, one operand is converted at execution time of the compare instruction to a format consistent with the other operand. The apparatus determines whether the contents of the first operand is greater than, less than, or equal to the second operand.</p> |
