*	History : 19/01/2002 written for the first time
*		  28/01/2002 __hprintf written
*
*	Known errors : 1)
*                      When the function hprintf returns it sets textcolor
*		       to LIGHTGRAY which may be undesirable .
*		       So double check your text colors after
*		       you have called any fuction in HPRINTF.H
*		       2)
*		       In Function __hprintf() , a flag char (hb[i] or he[i])
*		       cannot follow a hb[i] , If so the flag gets printed
*		       and the highlight continues ...
*		       There is no way to print a flag char.
*		       
*       Bug Reporting : I do not support hprintf() anymore. Moreover since
*		       I generated it , I cannot support it.
*		       If you see any bugs in __hprintf() plz report it to me.
*		       Since it is an interseting function i will try to fix it.
*		       Use either:
*		        1) mailto  : rajeshgoli@yahoo.com
*		        2) http://www.rajeshgoli.com/feedback
*		       Put "__hprintf() bug report" on subject line. Thank you.

   u can do so using the following code .

   using hpgen.c u can generate the whole code

   hprint() is too long and not provided here
   you can download hpgen.c and compile & run it
   to get that function.
