OPS/REXX COMPARISONS FALL INTO ONE OF THREE CATEGORIES: STRICT, NORMAL,
AND PSEUDO. STRICT AND NORMAL OPERATORS TRANSLATE DIRECTLY INTO REXX
OPERATORS, BUT EASYRULE CREATES COMPOUND REXX STATEMENTS TO IMPLEMENT
PSEUDO OPERATERS.
ALL COMPARISONS, NORMAL, STRICT OR PSEUDO, CAN BE NEGATED BY USING A
OR PREFIX CHARACTER. FOR EXAMPLE, = MEANS "NOT EQUAL," AND BW MEANS
"DOES NOT BEGIN WITH." LIKEWISE = AND BW HAVE SIMILAR MEANINGS.
