    // If the nonnumeric operand is an elementary item or a literal, the compiler treats the numeric
    // operand as if it had been moved into an alphanumeric data item the same size as the numeric
    // operand and then compared. This causes any operational sign, whether carried as a separate
    // character or as an overpunched character, to be stripped from the numeric item so that it
    // appears to be an unsigned quantity.

    // characters, indicating that there are assumed integer positions that are not actually
    // present, they are filled with zero digits. Thus, an item with a PICTURE character-string of
    // S9999PPP is moved to a temporary location where it is described as 9999999. If its value is
