Am still completing my expert system or rather diagnostic system in
Common Lisp and bit stressed right now. I have saved my cases into lisp
structures using defstruct into a textfile. THe question is :

1. How to extract  structures one by one from the textfile rather than
the whole bunch of them?

2. And how do i index them and append them to a database called
*example-database* (which consist of previous cases using
defstruct)after a new case is saved into the textfile? How do I update
it to *example-database* after extracting from the textfile?

Please help,
tq 
aston
