  We give a closed-form expression for the associated Meixner polynomials from
which we derive closed-form expressions for the associated Charlier and
Laguerre polynomials by a limit procedure. These formulas are then used to
derive generating functions of these polynomials. Also, we investigate the
Mehler-Heine type asymptotic formulas for the associated Meixner and Charlier
polynomials. Some applications and consequences of our results are also
mentioned.
