.nf
 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\&.

\fBParameters\fP
.RS 4
\fIPATH\fP 
.PP
.nf
          PATH is CHARACTER*3
          The LAPACK path name of subroutine SUBNAM\&.
.fi
.PP
.br
\fISUBNAM\fP 
.PP
.nf
          SUBNAM is CHARACTER*(*)
          The name of the subroutine that returned an error code\&.
.fi
.PP
.br
\fIINFO\fP 
.PP
.nf
          INFO is INTEGER
          The error code returned from routine SUBNAM\&.
.fi
.PP
.br
\fIINFOE\fP 
.PP
.nf
          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\&.
.fi
.PP
.br
\fIOPTS\fP 
.PP
.nf
          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'\&.

.nf
          M is INTEGER
          The matrix row dimension\&.
.fi

.br
\fIN\fP 
.PP
.nf
          N is INTEGER
          The matrix column dimension\&.  Accessed only if PATH = xGE or
          xGB\&.
.fi
.PP
.br
\fIKL\fP 
.PP
.nf
          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\&.
.fi
.PP
.br
\fIKU\fP 
.PP
.nf
          KU is INTEGER
          The number of super-diagonals of the matrix\&.  Accessed only

\fIN5\fP 
.PP
.nf
          N5 is INTEGER
          A fifth integer parameter, may be the blocksize NB or the
          number of right hand sides NRHS\&.

\fIIMAT\fP 
.PP
.nf
          IMAT is INTEGER
          The matrix type\&.

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

\fINERRS\fP 
.PP
.nf
          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\&.
