Assignment 6

                             Date : 11 Oct 2000

                           Due Date : 20th Oct 2000

Create a simple text editor which can (at least theoretically) handle
huge files.  It takes a file name as a command line argument,
and it takes commands:
  :i     inserts a new line (typed next) after current line
  :g n   go to line number n
  :r     replaces current line by contents of line typed in next
  :d     deletes current line
  :p m n prints lines m through n

The file is to be stored as a database, with one object per line.
Lines are to be linked together in a linked list.

To avoid name clashes in the database, your file names MUST be of the form
   loginname-filename

Submit a printout of your program.

Please work with each other to figure out how to use versant
and the demo programs, but you must write the assignment on your own.

Note :

Versant is installed on pro-26.
Its path is /usr/local/versant

Setup instructions :

Add following lines in your .profile.

export PATH=/usr/local/egcs-1.1.2_obj/bin:/usr/local/versant/5.2.2/linux/bin:$PATH

export LD_LIBRARY_PATH=/usr/local/versant/5.2.2/linux/lib:/usr/local/versant/5.2.2/linux/lib/linux:/usr/local/versant/5.2.2/linux/lib/linux.chk

The demo files are in 
      /usr/local/versant/5.2.2/linux/demo
