Something similar can be done automatically with namelists.  This would 
require you to reformat your input file to follow the standard namelist 
format.

Otherwise this kind of code is not hard to write in Fortran (or any 
programming language for that matter).  Just read the first element from 
the line, then use SELECT ... CASE to decide which variable to drop the 
value from the second column in.

NB this is not a forum for general programming questions.
