hi,
        The text file that you have seems to have a regular pattern as to how the
characters appear.
Whenever this happens it is not that hard to retrieve data from the file. I
guess you can figure it out. If not let me know and send me a sample file i
will try to whip up a script which shows how to do it.

         At the start of the program parse all the data and store it in a list
format and based upon that data make your searches. This would work fast and
at the same time this is the best option if you have only one person using
this file at a time. otherwise you might end up with many user having
differing sets of data. All this is usually taken care by database engines
so if it is complex i would suggest that you use a database.

        See you
                vijay
