title: Reading a two dimensional array
body: <p>I'm trying to read a two dimensional array (30.7) from a external file in Fortran 90 as  </p>
  
  <pre><code>READ(*,*)Fname
  
  OPEN(UNIT=10, FILE=Fname, ACTION="READ")
  
     DO i=1,30
  
        READ(10,*)(indices(i,j),j=1,7)
    END DO
  </code></pre>
  
  <p>Data has some missing values represented as blank. When I read data into array <code>(,*)(indices(i,j))</code>, it assigns <code>0.00</code> for missing data. How to over come this problem? Attaching the data below.</p>
