  Explicit solutions for the three-term recurrence satisfied by associated
continuous dual $q$-Hahn polynomials are obtained. A minimal solution is
identified and an explicit expression for the related continued fraction is
derived. The absolutely continuous component of the spectral measure is
obtained. Eleven limit cases are discussed in some detail. These include
associated big $q$-Laguerre , associated Wall, associated Al-Salam-Chihara,
associated Al-Salam-Carlitz I, and associated continuous $q$-Hermite
polynomials.
