Just a guess, but...
Assuming you are accessing a FoxPro data source (as you suggest in another
thread) this limitation is probably imposed by the method Word uses to
connect to the data. Word always used to connect to .dbf files using Jet
(Access) . Jet uses "installable ISAMs (IISAMs) to connect to "foreign" data
sources such as dBASE. The Jet IISAM is designed to connect to various
versions of dBASE, up to version 5 (V) I think. My guess is that all those
versions of dBASE are so old that they only allow the old DOS 8.3 filename
format and that that is the source of this limitation.
I assume that as FoxPro developed, this limitation was relaxed, but that the
IISAM has not been updated to allow for the changes.
For recent FoxPro files (whether .dbf or .dbc) you have to use the
appropriate ODBC or OLEDB driver for FoxPro (these can be downloaded from
the Microsoft web site).
