Cabibbo favored and singly Cabibbo suppressed decays of charmed mesons have been observed and studied in detail. To date, however, there is no unambiguous evidence for doubly Cabibbo suppressed decays (DCSD). The MarkIII experiment has previously reported results for wrong sign D{sup 0} decays which could be interpreted as evidence for enhanced DCSD. The authors report here preliminary results of a search for the decay chains D*{sup +}{r_arrow}D{sup 0}{pi}{sup +}, D{sup 0}{r_arrow}K{sup +}{pi}{sup {minus}}, D{sup 0}{r_arrow}K{sup +}{pi}{sup {minus}}{pi}{sup 0} and D{sup 0}{r_arrow}K{sup +}{pi}{sup {minus}}{pi}{sup {minus}}{pi}{sup +} using 1.8 fb{sup {minus}1} of data recorded with the CLEOII detector.
