If you look at the TMemo properties you'll find CaretPos, this however gives
you a TPoint object.

To do this you ca use the SelStart, SelLength and SelText properties.

     if (Memo->SelStart > 0)
     {
        int iSelStart = Memo->SelStart;
        int iSelLength = Memo->SelLength;

        Memo->SelStart--;
        Memo->SelLength = 1;
        AnsiString sChar = Memo->SelText;

        Memo->SelStart = iSelStart;
        Memo->SelLength = iSelLength;

        ShowMessage(sChar);
     }
