Demo programs C++ text files for a PC using Windows95

  Load a large file range.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/ range 
  puts all the component files in a new directory: range

  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.

  After giving the unzip command, you have a number of
  .h and .cc files in your range directory, the TeX
  language description file describe.tex, and also a
  makefile for creating executable files.
  Enter the range directory by the MSDOS command 
      cd \range
  
  If you have Borland's DOS C++ compiler for Win32, 
  then the MSDOS command
      make
  will constuct executable versions of all the demo programs.
  If you are using some other C++ compiler system having
  a make command, you will need to change the beginning lines
  of the  makefile that define the various compiler commands
  in order to get the make command to work correctly with your
  compiler system. 

  After make executes, you can use the MSDOS command 
      problem
  to call any of the demo programs.
