Introduction
The object PKS 0237-23 was identified as a quasar by
Arp et al. (1967).
They reported five emission lines in its spectrum and interpreted the spectrum on the redshift hypothesis
as having an apparent redshift of about 2.22. This quasar has played an important role in
the history of quasars. So many absorption lines were found in the spectrum of this
quasar that multiple redshift hypothesis was advanced to account for them. In this paper
we identify the emission and absorption lines in the spectrum of this quasar on the basis
of the plasma-laser star (PLS) model of quasars (Varshni,
1973,

1975a,
1977a,
1977b,

1985,
1988a,
1988b,
1988c,
Varshni and Lam, 1976,

Our theory does away with the artificial assumption of redshifts. Laser action is responsible
for the broad emission lines.
