!> 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
!> END IF
!> 

PATH

!>          PATH is CHARACTER*3
!>          An LAPACK path name for testing.
!> 

NMATS

!>          NMATS is INTEGER
!>          The number of matrix types to be used in testing this path.
!> 

DOTYPE

!>          DOTYPE is LOGICAL array, dimension (NTYPES)
!>          The vector of flags indicating if each type will be tested.
!> 

NTYPES

!>          NTYPES is INTEGER
!>          The maximum number of matrix types for this path.
!> 

NIN

!>          NIN is INTEGER
!>          The unit number for input.  NIN >= 1.
!> 

NOUT

!>          NOUT is INTEGER
!>          The unit number for output.  NOUT >= 1.
