NAME
       dgssuo - Provide general sparse solvers SPSOLVE and SuperLU a user-sup‐
       plied permutation for ordering.

SYNOPSIS
	SUBROUTINE DGSSUO ( PERM, HANDLE, IER )

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

PURPOSE
       DGSSUO - Provide general sparse solvers SPSOLVE and SuperLU a user-sup‐
       plied permutation for ordering.	Must be called after DGSSIN() (sparse
       solver initialization) and in place of DGSSOR() (sparse solver order‐
       ing).

PARAMETERS
       PERM(NEQNS)  - INTEGER array
	       On entry, PERM(NEQNS) is a permutation array supplied by the
	       user for the fill-reducing ordering.  Unchanged 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 num‐
	       bers set by this subroutine:

		-201 : Failure to dynamically allocate memory.
		-500 : Invalid calling sequence - need to call DGSSIN first.
