A condition is programmed between the [ and ] brackets in the following
format:

[A EQ B]

where:

- A and B represent some numerical value

- the values for A and B are in the form of some mathematical equation

or in the form of a paramacro parameter

Example 20.6 illustrates the use of the conditional operators found in
Table 20.C.
