3.3.3 RELATIONAL OPERATOR
Relational operators are used to compare two values. The result of the comparison is
either “True” or “False”. This result may then be used to make a decision regarding
program flow.

Sample Expression
=
Equality
A% = B%
< >
Inequality
A% < > B%
> <
Inequality
A! > < B!
>
Greater than
A% > B!
<
Less than
A! < B!
> =
Greater than or equal to
A% > = B%
< =
Less than or equal to
A% < = B%
3.3.4 LOGICAL OPERATOR
Logical operators perform tests on multiple relations and Boolean operations. The logical
operator returns a bit-wise result which is either “True” (not zero) or “False” (zero). In an
expression, logical operations are performed after arithmetic and relational operations.
