IF

Redirect to:

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

Syntax

IF evaluation THEN {code}

The evaluation by IF must be true for the {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 one line of code, 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 (an 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 execute multiple statements after THEN.
