 Salut

You can use the RETURN keyword !

Return have two act in gambas :
 - simply RETURN to leave the sub
- RETURN $result       to return a function result


Exemple for function :

in vb 

Public Function Weather (Value as Integer) as String

  if Value = 1 then 
    Weather = Sunny
    Exit Function
  End if  

    Weather = Cloudy
End select

End Function


The same in Gambas : 

PUBLIC FUNCTION Weather (Value as Integer) as String

  IF Value = 1 THEN  RETURN Sunny  
  RETURN Cloudy

End select

END

Gambas is great !
