title: Interpret strings as variable names in Fortran
body: <p>I'd like to access a real variable with a name equal to a string of characters that I have. Something like this (I'll make the example as clean as possible):</p>
  
  <pre><code>character(len=5) :: some_string
  real :: value
  value = 100.0
  some_string = 'value'
  </code></pre>
  
  <p>At this point, how do I create an association between the character array <code>value</code> and the name of my real variable, value, so that I can write the value of 100.0 by referring to the string <code>some_string</code>?</p>
