Abstract: Piecewise domains which are right orders in semiprimary rings are characterized. An example is given showing the result obtained is ``best possible". A further example is obtained of a prime right Goldie ring possessing a regular element which becomes a left zero divisor in some prime overring. This example leads to the construction of a PWD R not satisfying the regularity condition, but for which $ R/N(R)$ is right Goldie.
