If the condition is <literal>False</literal>, and an <emph>ElseIf</emph> statement follows, %PRODUCTNAME Basic tests the next expression and executes the following statements if the condition is <literal>True</literal>. If <literal>False</literal>, the program continues either with the next <emph>ElseIf</emph> or <emph>Else</emph> statement.
