/* This short program uses Less-Than-Or-Equal-To-Zero
 * to create the various signed comparison operators.
 *
 * The reason for this program is to understand how
 * those operators can be implemented on a SUBLEQ
 * One Instruction Set Computer.
 *
 * It is trivial to construct addition, subtraction
 * and branching with the SUBLEQ machine, but the
 * comparison and bitwise operators are more complex.
