FUNCTION: IF conditional statement
DESCRIPTION:
The IF command is used in conjunction with an ENDIF command to form an IF conditional
statement. The arguments consist of one or more conditional statements and each
condition must be enclosed with parenthesis (). If the conditional statement(s) evaluates
true, the command interpreter will continue executing commands which follow the IF
command. If the conditional statement evaluates false, the controller will ignore
commands until the associated ENDIF command OR an ELSE command occurs in the
program.
ARGUMENTS: IF (condition)

Conditions are tested with the following logical operators:
< less than or equal to
> greater than
= equal to
<= less than or equal to
>= greater than or equal to
<> not equal
Note:
Bit wise operators and & can be used to evaluate multiple conditions.
