Relational operators

Relational operators compare two values and return a logical (TRUE or FALSE) result. They can be used to compare numbers, character strings, or numerical and character variables.

Relational Operator	What it means
=	Equal to
<>	Not equal to
<	Less than
>	Greater than
<=	Less than or equal to
>=	Greater than or equal to

The following table contains some examples of how you might use relational operators in an expression.

Expression	What it does
Fuel > 15	Compares the value of custom variable `Fuel` to 15, returning a value of `TRUE` or `FALSE`.
Topic > 1	Returns a value of `TRUE` if the custom variable `Topic` is greater than 1; otherwise returns a value of `FALSE`.
Note number <= Total	Returns a value of `TRUE` if `Note number` is less than or equal to `Total`; otherwise returns a value of `FALSE`.
Completed = False	Compares the value of the custom variable `Completed` with `False`. If `Completed` is `FALSE`, returns a value of `TRUE`; if `Completed` is `TRUE`, returns a value of `FALSE`.
Number of lines = 15	Returns a value of `TRUE` if the custom variable `Number of lines` equals 15; otherwise returns a value of `FALSE`.

Notice that in the last two examples the equal sign (=) is used rather than the assignment operator (:=). The assignment operator is used to assign a value to a variable. The equal sign (=) is used to compare two values or variables.
