I need to separate last child folder from windows path. For example from C:java_11 separate java_11. I have this function :

function parseJavaHome(JavaHome:String) : String;
var lastPosOfSlash: Integer;
var tmp : String;
var slash: char := '';
var vCharacter : char ;
var counter: Integer := 0;
begin

   for vCharacter in JavaHome do
   begin
      counter := counter + 1;
      if vCharacter = slash then
      begin
      lastPosOfSlash := counter;
      end;
   end;

   for i:= lastPosOfSlash to Length(JavaHome) do
   begin
       tmp := tmp + JavaHome[i];
   end;

   Result:= tmp;
end;

end;

But compilation fails on line var slash: char := ”; (line 1224) It returns me this error:

Error on line 1224 in C:UserspkostrouIdeaProjectspackstation_adm_coreinstallerbuildadm-application-setup.iss: Column 21:
