title: Is '(A)' a keyword?
body: <p>I have a doubt about Fortran code. Is "A" a keyword? I found this character used in write and format commands but I can't find some specific documentation about it. Here are some examples:</p>
  
  <pre><code>CHARACTER *10  name
  write(*,1) name
  1 format   ("   Your name is ",A)
  </code></pre>
  
  <p>or</p>
  
  <pre><code>end = LNBLNK(string)
  write(4,'(A)') string(1:end)
  </code></pre>
