*
* =========== DOCUMENTATION ===========
*
* Online html documentation available at

*
* Definition:
* ===========
*
* SUBROUTINE ALAREQ( PATH, NMATS, DOTYPE, NTYPES, NIN, NOUT )
*
* .. Scalar Arguments ..
* CHARACTER*3 PATH
* INTEGER NIN, NMATS, NOUT, NTYPES
* ..

*
*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> 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
*> \endverbatim
*
* Arguments:
* ==========
*
*> \param[in] PATH
*> \verbatim
*> PATH is CHARACTER*3
*> An LAPACK path name for testing.
*> \endverbatim
*>
*> \param[in] NMATS
*> \verbatim
*> NMATS is INTEGER
*> The number of matrix types to be used in testing this path.
*> \endverbatim
*>
*> \param[out] DOTYPE
*> \verbatim
*> DOTYPE is LOGICAL array, dimension (NTYPES)
*> The vector of flags indicating if each type will be tested.
*> \endverbatim
*>
*> \param[in] NTYPES
*> \verbatim
*> NTYPES is INTEGER
*> The maximum number of matrix types for this path.
*> \endverbatim
*>
*> \param[in] NIN
*> \verbatim
*> NIN is INTEGER
*> The unit number for input. NIN >= 1.
*> \endverbatim
*>
*> \param[in] NOUT
*> \verbatim
*> NOUT is INTEGER
*> The unit number for output. NOUT >= 1.
