Now you can edit the files autoexec.nt and config.nt
In order to make foxpro run, you need to add codes as follow:

In Autoexec.NT, you should add:

path=%path%;f:\optic;f:\fpd26

That is the path to your program, data, and Foxpro program. You could change the directory according to yours.

When you run foxpro programs, you could find "Too Many Files Open" Error. To resolve this problem, you should add 2 lines in your config.nt:

files=240buffers=60

That's it.
