A file has multiple records each having three 30-bit long
fields(field1,field2,field3).There is also a lookup
file,LOOK_UP.dat.Now, we need to consider only the
last ten digits of field1 and lookup the file LOOK_UP.dat.
If there a match then field2 and field3 should replaced
with corresponding data from the lookup file. otherwise
that particular record,for which there is no match, should
be stored in a seperate file.

If we would knew the structure of LOOK_UP.dat (like the
structure of file is mentioned) then the script could be
more precisely written.
