This keyword precedes a condition, must be followed by then and may optionally be followed by else.


Official documentation: FreePascal documentation

If then

  if condition
    then true_statement
    else false_statement;

Condition is a Boolean expression that evaluates to true or false. true_statement is executed if condition evaluates to true. false_statement is executed if condition evaluates to false. An error occurs if condition does not evaluate to a boolean value.

More statements in "if then" statement

If you need two or more statements for true_statement or false_statement, place them within a begin ... end Block.
