This sample utility will do the following:
   
   1. Scan a drive of all directories, and place them into a user interface
      that resembles an old version of "Norton's Change Directory" ver. 4.5
   
   2. Has the ablitity to show files in current highlighted directory, by
      either pressing [enter] or the [spacebar]. If the directory is empty
      a message appears informing you of the fact.
   
   3. On exiting the utility you'll be prompted to change to the desired
      directory. If you forced the program (from dos) to read another drive
      otherthan the current working drive, then the program will also do a
      drive change also, besides the directory change!
   
   4. The utility will scan the current working drive in default mode, which
      means that there were no dos parameter to scan another drive.
      
      Valid startups
      
      Scan current drive
      VTREE [enter]
      
      Scan drive E:
      VTREE e:\ [enter]   
      
      Ask for help
      VTREE /? [enter]
      
   5. Note that there is room for more errorchecking and improvement to the
      code, like using a third-party library for some coding that was done
      in Clipper ie. nanfor.lib's FT_DEFAULT(), FT_CHDIR(), FT_SHADOW() etc.
   
   
   6. The program also serves novice programmers as a teaching tool for
      studying recursion, code-blocks, manipulating arrays, working with
      achoice (TBrowse is better but I went for simplicity) and learning to
      code without depending so much on third-party libraraies. Its always
      good to have source code, which many libraries do not give out so fast!
      Speaking of libraries, I would highly recommend that you get your hands
      on the lastest copy of NANFOR.LIB from Compuserve's Clipper forum by
      typing GO CLIPPER from any CIS prompt. This library is full of great
      stuff that was developed by many top notch programmers for FREE!
      FUNCKy II by dLESKO does not give out source code but is the best I've
      seen for a wide array of functions. Grumpfish by Greg Lief is 99.8%
      pure Clipper source and is included with the library..
      (Am I starting to sound like a advertisment) Nuff Said!
   
   7. The program is considered to have no real copyright, and you may alter
      it so long as the original programmers names appear at the top of each
      of the .prg, .h files (add a notch into the headers if you make a nice
      change or addition)
