title: Converting a string to an integer in Fortran 90
body: <p>I know that <code>IACHAR(s)</code> returns the code for the ASCII character in the first character position of the string s, but I need to convert the entire string to an integer. I also have a few number of strings (around 30 strings, each consists of at most 20 characters). Is there any way to convert each one of them to a unique integer in Fortran 90? </p>
