HI folks,   
      
   I've been ahving so much fun!!!   
      
   Revamping my ham radio net control logger a little bit,   
   easier menu driven interface for not regular users, and for   
   Kathy without having to write separate programs for both of   
   us.   
      
   ONe of the legal requirements is that one identifies his/her ham station at   
   ten minute intervals or more frequent here in the U.S>   
      
   so, various menu items plug the minutes past the hour in a   
   file which we can then plug into an environment variable   
   using HOrst's nset.   
      
   So I'm using TImo's function evaluator to subtract the   
   number %ID% captured from this file from current minutes   
   past the hour (stuffed into another env var) and think this   
   should be real simple.  Just have the next line in the batch do   
      
   fn /b %COUNTER%-%ID% >> checknum.txt   
      
   tHen of course we remove the decimal point from checknum.txt and replace it   
   with white space, so we can   
   stuff that whole number into another env var for ifnumber to chew on compared   
   against the value of %LEGAL% which will of   
   course be ten.   
      
   But, Timo's function evaluator was giving me weird numbers,   
   almost like it couldn't add or subtract anymore.   
      
   So, we played with it in test mode for awhile, then   
   discovered that if we express the equation fully algebraic   
   as in   
      
   fn /b %COUNTER%+-%ID% >> checknum.txt   
      
   we suddenly get the right answer.   
      
      
      
   Fun with my morning coffee.   
      
      
      
      
   Regards,   
              Richard
