        DATA INPUT HELP SCREEN FOR PROGRAM "LINEQ":
        For  an  example  of  the  program  input  data,  consider  the
        following four linear equations.
      
           20.1(X1) -  7.3(X2) +  0.0(X3) +  1.2(X4) = -98.9
           12.3(X1) +  0.0(X2) +  5.5(X3) +  0.0(X4) =  57.4
            2.5(X1) + 10.0(X2) - 35.5(X3) +  2.0(X4) = 127.3
            0.5(X1) + 19.1(X2) +  0.0(X3) +  0.0(X4) = 217.1
      
        The input data file for solving these  equations  is  a  matrix 
        containing the coefficients from the left side of the equations 
        and the results from the right side as is demonstrated below:
      
           20.1       -7.3        0.0        1.2       -98.9
           12.3        0.0        5.5        0.0        57.4
            2.5       10.0      -35.5        2.0       127.3
            0.5       19.1        0.0        0.0       217.1
          
        The data is free format, and the only requirement is  that  the 
        data be in the proper sequence  and  that  there  be  the  same 
        number of equations as unknowns.  After  running,  the  program 
        will  display  results for X1, X2, X3, etc.
