IF

IF statements make Boolean True or False program evaluations to automate program decision making.

Syntax: IF evaluation is true THEN execute code

• The evaluation by IF must be true for the THEN code to be run.
• IF statements can also have alternative evaluations using ELSEIF and ELSE conditions.
• When the IF statement and/or code to be run is more than code line, an END IF statement MUST be used.
• With multiple code lines to run, end the IF statement with THEN and place all of the code on lines below that line.
• With multiple code lines to run (a IF...END IF block), the IF statement and END IF statement must be the first statement on the line!
• The IDE may point to an error in a loop or somewhere else if you forget to use END IF (typically a PROGRAM FLOW ERROR! message).
• Use colons to change multiple values in a one line IF statement. You cannot use AND on the other side of THEN!
