tip

If statements can be shortened to one line when using single statement blocks.



  If condition Then statement [Else statement]

Parameters:

The If...Then statement executes program blocks depending on given conditions. When LibreOffice Basic encounters an If statement, the condition is tested. If the condition is True, all subsequent statements up to the next Else or ElseIf statement are executed. If the condition is False, and an ElseIf statement follows, LibreOffice Basic tests the next expression and executes the following statements if the condition is True. If False, the program continues either with the next ElseIf or Else statement. Statements following Else are executed only if none of the previously tested conditions were True. After all conditions are evaluated, and the corresponding statements executed, the program continues with the statement following EndIf.

    sToday = Right$(sToday, 4)+ Mid$(sToday, 4, 2) + Left$(sToday, 2)
    If sDate < sToday Then
        MsgBox "VanhentumispÀivÀ on ohitettu"
