I have started writing a app which saves information on our customers at work and saves the data as a record to disk. It is supposed to be tracking our service calls and then we can review, at the end of a twelve month period, how many calls a particualar client has made and what the call involved.
The record is "indexed" by client number. What I want to do
is scan through the file, sort it and remove any duplicates at the same time. The most important part is just sorting - by client number.
Any help would be appreciated.
