2.   Roy Allen ,of Mill Valley, California  combined a Game with 
     Pascal/Z's direct File access tï  comå  uð  witè aî excellenô 
     Demo®  Thå gamå  ió  aî  olä favorite called ANIMALS. 
     Everything that ANIMALS learns is containeä  iî thå paiò oæ 
     fileó calleä Beasts®  Iæ fileó  bù those names are not found 
     on the currently-logged disk, the program will create a new 
     set of files. It starts out with only two animals so you'll 
     have to have your kids teach it  some.

     TERMIO.LIB                    Edited version  that is to be

     Ray also included a clever little game to demostrate how his
     INSTALL program works. It looks for the terminal data file
     "TERMIO.FIL". The game moves three characters around on the

       The bench check that was used to compare MT+ and Pascal/Z
     wasn't correct in that Byte article. So when I looked at it
     I cleaned it up but the reason I am including it here is not
     the bench check aspect but the algorithm. It had some pretty
     shifty thinking. So I included it just as a curosity item.

       MILEAGE came out of the class room. I cleaned it up and
     adapted it to Pascal/Z. It'll figure out your MPG.
