FranzB 0 Posted April 17, 2022 would like to understand the difference in the uses statement between uses System.Types; vs. uses Types; After a long time I need to recompile an application which has already been successfully compiled for the LINUX OS. Today the compiler claims I need to change from Types only to system.Types . This is basically not a big deal but I want to understand why this happened. my unit scope names are definded as : FMX;Winapi;System;Data.Win;Datasnap.Win;Web.Win;Soap.Win;Xml.Win Share this post Link to post
