c*    Subroutine to load an entire linear system.
c*
c*    <PARAMETER LIST>
c*
c*     Input:
c*      lu - logical unit from which to read
c*
c*     Output:
c*      a - coefficient matrix
c*      ia - integer vector containing info about how "a" is stored
c*        NOTE: see description of ia below
c*      ja - map array
c*      x - vector of unknowns
c*      b - vector containing right-hand side
c*      status - return status
c*        -1  ==>  invalid argument(s)
c*         0  ==>  success
