SUBROUTINE ALAREQ( PATH, NMATS, DOTYPE, NTYPES, NIN, NOUT )
*
* -- LAPACK test routine (version 3.0) --
* Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
* Courant Institute, Argonne National Lab, and Rice University
* February 29, 1992
*
* .. Scalar Arguments ..
CHARACTER*3 PATH
INTEGER NIN, NMATS, NOUT, NTYPES
* ..
* .. Array Arguments ..
LOGICAL DOTYPE( * )
* ..
*
* Purpose
* =======
*
* ALAREQ handles input for the LAPACK test program. It is called
* to evaluate the input line which requested NMATS matrix types for
* PATH. The flow of control is as follows:
*
* If NMATS = NTYPES then
* DOTYPE(1:NTYPES) = .TRUE.
* else
* Read the next input line for NMATS matrix types
* Set DOTYPE(I) = .TRUE. for each valid type I
* endif
*
* Arguments
* =========
*
* PATH (input) CHARACTER*3
* An LAPACK path name for testing.
*
* NMATS (input) INTEGER
* The number of matrix types to be used in testing this path.
*
* DOTYPE (output) LOGICAL array, dimension (NTYPES)
* The vector of flags indicating if each type will be tested.
*
* NTYPES (input) INTEGER
* The maximum number of matrix types for this path.
*
* NIN (input) INTEGER
* The unit number for input. NIN >= 1.
*
* NOUT (input) INTEGER
* The unit number for output. NOUT >= 1.
