Hello all

I am working with random data files in Novell Netware LANs since years. With
this network I use a module called FABS PLUS for locating records using
index files: when you want a record you call Fabs giving a key (e.g. part
number, cliente code, insertion date, ...), then Fabs search in its b-trees
and tells to you what position has data in your random file. For this system
to work you must inform to Fabs of each change you do in the data file.

Well, the problem is Fabs is an old product that work well under Netware if
you mark index files 'Shareable'  with FLAG S command, but don't work with
Windows NT server. I have been looking for another product for same work and
I've found BPLUS: same thing basically but written in C language and with
source. So I adapted my interface module to use any of the products and
compile for Netware or for NT.

But this package (BPLUS) don't work fine when two users try to modify the
same file. I have written a simple 'semaphore' system to wait until no other
proccess is trying to write but this is too bad when two operators must
enter data continuously.

I would like to know if there are other packages for this work.
Have you forgotten all this stuff and now are happy using a true database?
Are you all working with cliente/server tools?
Do someone knows a book/FAQ/web page/loquesea about data files and networks?

Thanks.
Falo
