   TRNOPT creates a template of the TRNSYS input file replacing certain 
parts of the input file with special characters. When GenOpt chooses a 
new set of values to try, TRNOPT replaces those special characters with 
the new values. This is a bit of an oversimplification of course.

   The error that you are getting is a bit odd; the VERSION keyword 
occurs right at the very beginning of the TRNSYS input file and 
indicates which version of TRNSYS the dck was intended for. If you have
