I am interested in find a imple method to handle files under basic.
My application requires me to keep tracks of customer's data as well as
Invoices. How do I maintain a reasonably large database with Basic?
Especially when the data such as address contains "commas -," and
chr$(10) and chr$(13).
Another problem is that the length of each invoice is not fixed. Some
peopl buy for items than others. So obviously I couldnt use records.
I figure that binary file access is the only way. Any suggestions would
be greatly appreciated.

Another consideration is whether it is network compatible.

I am wondering if I could write the database into a DBASE compatible
file format (.DBF). anyone with any information?

I have written several similar applications using PDS 7.1, which has a
good reliable ISAM database method internal to the language - but it is
not network compatible.  Used the database to hold client/inventory data.
One field points to a seperate disk file which is the invoice in ASCII text.

There is a replacement ISAM for PDS called E-Tree, from EllTech Technologies,
that can do networks, and has a variable length field option, which can hold
an invoice, along with the CRs and LFs.  There are many other libraries
available, a third party library is definately the way go, here.
