NAME

     zgssrp - Return permutation used by the general sparse
     solver.

SYNOPSIS

      SUBROUTINE ZGSSRP ( PERM, HANDLE, IER )

      INTEGER           PERM(*), IER
      DOUBLE PRECISION  HANDLE(150)

PURPOSE

     ZGSSRP - Returns the permutation used by the solver for the
     fill-reducing ordering.

PARAMETERS

     PERM(NEQNS)  - INTEGER array
             Undefined on entry.  PERM(NEQNS) is the permutation
             array used by the sparse solver for the fill-
             reducing ordering.  Modified on exit.

     HANDLE(150)  - DOUBLE PRECISION array
             On entry, HANDLE(*) is an array containing
             information needed by the solver, and must be passed
             unchanged to each sparse solver subroutine.
             Modified on exit.

     IER       - INTEGER
             Error number.  If no error encountered, unchanged on
             exit.  If error encountered, it is set to a non-zero
             integer.  Error numbers set by this subroutine:

              -600 : Invalid calling sequence - need to call ZGSSOR first.
