Syntax: if <condition> <statement1> else <statement2> end

Description

Use if to implement a conditional statement. The condition expression must be bool type. Otherwise, the condition is ill-formed.

When <condition> evaluates to true, <statement1> executes. If <condition> is false, <statement2> executes.

Example:

if tau>45ns mwpulse t180 else wait t180 end
