title: Skip a line from text file in Fortran90
body: <p>I'm writing in fortran (90). My program must read file1, do something with every line of it and write result to file2. But the problem - file1 has some unneeded information in first line.</p>
  
  <p>How can I skip a line from input file using Fortran?</p>
  
  <p>The code:</p>
  
  <pre><code>open (18, file='m3dv.dat')
  open (19, file='m3dv2.dat')
  do
    read(18,*) x
    tmp = sqrt(x**2 + 1)
    write(19, *) tmp
  end do
  </code></pre>
  
  <p>First line is a combination of text and numbers.</p>
