{   This is a fast and dirty program to print out source code listings for
    Turbo Pascal 4.0 thru 5.5 listings.  It doesn't do anything too fancy.  It
    does print out a header with the name of the file, the page number, and
    the date and time the file was printed.  You can use the date and time to
    determine if the file on disk was updated since the printout.  One other
    attraction is that it counts lines will only print 59 lines on a page. It
    also allows a forced new page command in the listings.  By placing a (*\*)
    in the first 5 columns of any line of the program will force a new page at
    that point.  The backslash in a comment symbol was chosen since the
    compiler will treat it as a comment and will ignore it.  The program uses
    myprint which is a unit containing a few control codes and procedures to
    implement them.  Myprint was done for a Gemini 10 printer, so the
    procedures should work with Epson printers as well.  I have tried it on a
    newer star printer (NX-2400 and it works perfectly.  If you have a
    different printer, just make your own myprint unit with codes which match
    your printer.  See myprint unit for details.

    Someday I may enhance this by adding more capabilities.

    My thanks to Jeff Flading who's ideas and efforts resulted in several
    improvements.

    To print source code using this program just compile it and then the
    the following at the DOS prompt:

                     TP4Print  X:YYYY\YYYYYYY\ZZZZZZZZ.ZZZ  I

   where the X is the optional drive specifier, the Y's represent the
   optional directory path info and ZZZZZZZZ.ZZZ represents the actual
   program name including the extension.  The program does not assume
   a defualt extension of PAS or anything else.  If the name has an
   extension, it must be included.  The I is an optional parameter.  If you
   put the I (or a small i will work) after the file name, only the
   interface part of the file will be printed.  For this to work, the source
   code must have a (*!*) located in the first 5 columns of a line. If this
   control code is encountered, the program will terminate and nothing more
   will be printed.  In all of my source code, this control code is placed
   before the implmentation part of the code.  Therefore, if you include the i
   after the file name, only the interface code will be printed

   I intend to add a few more bells and whistles later if I can think of any.  }
