I presume you forgot a Begin here.

With is not a good construct to use in Delphi. A google search of this ng
will turn up multiple threads as to why. I'd suggest a coding more like

var myStringList : tStringList;

. . .
myStringList : tStringList.Create;
try
    myStringList.Add ('hello');
    myStringList.Add ('world');
    . . .
    ShowMessage ('Count is ' + IntToStr (myCount (myStringList)));
    . . .
finally
    myStringList.Free;
    end;
. . .
