Executes a statement or statement block if the Boolean expression is true. If an ELSE statement is included and the Boolean expression is false, an alternate statement or statement block is executed. For an IF...THEN statement to be broken into more than one line, the first item on the next line must be THEN, AND, or OR. IF...THEN statements only apply to the next statement or statement block in a logic. Any statements outside of the BEGIN and END will execute normally. See BEGIN and END for examples.
Any logic.
<Boolean expression>
The condition to be tested.
THEN <statement 1>
The statement or block to be executed if the condition is true.
ELSE <statement 2>
The statement or block to be executed if the condition is false.
In the following example an IF...THEN...ELSE test is made to see if the simulation clock is less than eight hours. If so, the Client is routed to Office1, otherwise the Client is routed to Office2.
