SYMPTOMS
========

In Microsoft Visual C++, the .CPP extension can cause errors when it is used to
create a .PLB or .FLL file with the FoxPro 2.5 Library Construction Kit (LCK).

For example, using the .CPP extension to create a .FLL file (FoxPro for Windows
library) can cause the error "<path>\PROAPIML.LIB
(c:\dosdev\source\winapi16.c) : error L2029: '_FoxTable' : unresolved external",
where <path> is the path to PROAPIML.LIB.

RESOLUTION
==========

To avoid the error, do one of the following:

- Rename the program to have a .C extension.

-or-

- Declare FoxTable as external, as follows:


        extern "C" FoxTable _FoxTable =
        {
           (FoxTable FAR *) 0, sizeof(myFoxInfo) / 
              sizeof(FoxInfo), myFoxInfo
        };
