* Description:	This program will take standard input  (if no argument
*		specified in  command line) or  the specified  file as
*		form  template and  display   it  on  the terminal  to
*		perform basic form editing function.  It then generate
*		the Csh  or Bourne shell set script  on  stdout  to be
*		executed (ala tset -s).
*
*		This program is designed to  give programmer  an  easy
*		way of doing form filling in shell level.
