DescriptionEdit
function RightStr(const AText: AnsiString; const ACount: Integer): AnsiString; overload; function RightStr(const AText: WideString; const ACount: Integer): WideString; overload;
The RightStr function takes 2 parameters. The first parameter is the source string and the second is an index integer which counts backwards from the end of the string.
The result is a substring at the very end of the source string with the length given in the second parameter.

SubString := RightStr(SourceString, SubStringLength);
ShowMessage(SubString); //will show 'Wikia'
SubStringLength := 20; //length is more then the source string
SubString := RightStr(SourceString, SubStringLength);
ShowMessage(SubString); //will show the complete SourceString 'Delphi Wikia'
SubStringLength := -1;
SubString := RightStr(SourceString, SubStringLength);
ShowMessage(SubString); //If the SubStringLength is anything lower than 1 then then result will be empty
