.SH PURPOSE
PZGBTRS solves a system of linear equations
                                  or
.br
          A(1:N, JA:JA+N-1)' * X = B(IB:IB+N-1, 1:NRHS)
.br

where A(1:N, JA:JA+N-1) is the matrix used to produce the factors
stored in A(1:N,JA:JA+N-1) and AF by PZGBTRF.
.br
A(1:N, JA:JA+N-1) is an N-by-N complex
.br
banded distributed
.br
matrix with bandwidth BWL, BWU.
.br

Routine PZGBTRF MUST be called first.
