*
*                     Program to list C source files on an HP Laserjet Printer
*
*
*
* Filename     : HPLISTC.C
* Programmer(s): Jean J. Labrosse
*********************************************************************************************************
*
*
* Program use :
*
*        HPLISTC filename.ext [L | P] [>destination]
*
*        where :
*
*             filename.ext        Is the name of the file to list (with extension)
*             [L]                 Indicates that the printer will print in LANDSCAPE mode
*             [P]                 Indicates that the printer will print in PORTRAIT  mode (default)
*             [>destination]      Is the destination of the listed file, it can be:
*                                      >PRN        for the printer
*                                      >file.ext   for redirecting it to a file
*
* Note: This program is compiled using the Borland International C++ compiler Version 3.0
