I concur in the result and join in the Opinion of the Court to the extent that it adopts Commonwealth v. Shields, 247 Pa. Super. 74, 371 A.2d 1333 (1977), as controlling authority on the issue of whether the thirty day grace period allowed by Pa.R.Crim.P. 1100(d)(2) applies to each continuance granted to the defense.
