Executable demo progams for a PC using Windows95

  Load the large file pc_demo.zip
  to a convenient directory.  Enter that directory by giving
  the appropriate MSDOS command.

  If you have the MSDOS utility program unzip.exe,
  the MSDOS command
      unzip -d/ pc_demo 
  puts all the executable demo programs in a new directory: demo

  The two MSDOS commands
      cd \demo
      problem
  gives you access to all of the 28 demo programs. 

  If you do not have the MSDOS utility program unzip.exe
  for dissecting zip files, you can obtain it by
  loading the file unz520x.exe
  to a convenient directory, entering that directory
  by the appropriate MSDOS command, and giving the MSDOS command
      unz520x
  You then obtain unzip.exe and other explanatory files
  in that directory.
