NAME
       TESTING/LIN/alaerh.f

SYNOPSIS
   Functions/Subroutines
       subroutine alaerh (path, subnam, info, infoe, opts, m, n, kl, ku, n5,
           imat, nfail, nerrs, nout)
           ALAERH

Function/Subroutine Documentation
   subroutine alaerh (character*3 path, character*( * ) subnam, integer info,
       integer infoe, character*( * ) opts, integer m, integer n, integer kl,
       integer ku, integer n5, integer imat, integer nfail, integer nerrs,
       integer nout)
       ALAERH

       Purpose:


            ALAERH is an error handler for the LAPACK routines.  It prints the
            header if this is the first error message and prints the error code
            and form of recovery, if any.  The character evaluations in this
            routine may make it slow, but it should not be called once the LAPACK
            routines are fully debugged.

       Parameters
           PATH

                     PATH is CHARACTER*3
                     The LAPACK path name of subroutine SUBNAM.

           SUBNAM

                     SUBNAM is CHARACTER*(*)
                     The name of the subroutine that returned an error code.

           INFO

                     INFO is INTEGER
                     The error code returned from routine SUBNAM.

           INFOE

                     INFOE is INTEGER
                     The expected error code from routine SUBNAM, if SUBNAM were
                     error-free.  If INFOE = 0, an error message is printed, but
                     if INFOE.NE.0, we assume only the return code INFO is wrong.

           OPTS

                     OPTS is CHARACTER*(*)
                     The character options to the subroutine SUBNAM, concatenated
                     into a single character string.  For example, UPLO = 'U',
                     TRANS = 'T', and DIAG = 'N' for a triangular routine would
                     be specified as OPTS = 'UTN'.

           M

                     M is INTEGER
                     The matrix row dimension.

           N

                     N is INTEGER
                     The matrix column dimension.  Accessed only if PATH = xGE or
                     xGB.

           KL

                     KL is INTEGER
                     The number of sub-diagonals of the matrix.  Accessed only if
                     PATH = xGB, xPB, or xTB.  Also used for NRHS for PATH = xLS.

           KU

                     KU is INTEGER
                     The number of super-diagonals of the matrix.  Accessed only
                     if PATH = xGB.

           N5

                     N5 is INTEGER
                     A fifth integer parameter, may be the blocksize NB or the
                     number of right hand sides NRHS.

           IMAT

                     IMAT is INTEGER
                     The matrix type.

           NFAIL

                     NFAIL is INTEGER
                     The number of prior tests that did not pass the threshold;
                     used to determine if the header should be printed.

           NERRS

                     NERRS is INTEGER
                     On entry, the number of errors already detected; used to
                     determine if the header should be printed.
                     On exit, NERRS is increased by 1.

           NOUT

                     NOUT is INTEGER
                     The unit number on which results are to be printed.
