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.
