Allow arithmetic expressions in conditional statements.

Syntax 

     (no new syntax)

Parameters 

test-variable    The class of objects which can be specified as a test
                 variable is extended to include an arithmetic expression
                 (enclosed in square brackets) which will be evaluated
                 before the comparison is made.

value            The class of objects which can be specified as a
                 comparison value is extended to include an arithmetic
                 expression which will be evaluated before the comparison
                 is made.

Discussion 

This enhancement permits users to include arithmetic expressions on the
left and right hand sides of a boolean expression.

Example 

     1)  IF (AREA) = [(LENGTH)*(WIDTH)],[(BASE)*(HEIGHT)*.5],
                      [(3.1416)*(RADIUS)**2] THEN ...;

     2)  REPEAT
            FIND(SERIAL) STK-ON-HAND,STATUS
         UNTIL ((WEIGHT) > [(KILO-PER-METER) * (METERS)] AND
                (METERS) > (MIN-LENGTH) OR
                (PRICE) > [(UNIT-PRICE) * (KILO-PER-METER) * (METERS)]);
