    To display BACK softkey when no more character are left in the calulator editor

    Oct 20, 2004    REF: CRR 25755 xnkulkar
    Description: calculator -divide by zero operation is allowed.
    Fix:    Display "Not Allowed" message when user tries to divide a number by 0 and do not perform the
                 division. Also, show the editor again so that user can enter a number other than 0.
