File handling problem - modifying record

[pradyatwork]

I have to make a file (or a database I should say)in which I can read,write,append ---I can do these things easily.

The problem is that how I can rewrite at a particular location.I tried it but the next record is modified..

We can't help you without seeing your code. If there is a lot of it, try removing irrelevant parts.
