I found this accidentally... testing a converter of mine, which was supposed to convert old dos free tables into new tables with a dbc. It was using a directory name as the dbc name, and I forgot that and had a space in the name of the directory. And it still works!

Dbc() returns "M:\RAD\APVFP\OS DZ\DATA\OS DZ.DBC", and when I try to open a table, intellisense kicks in and gives me the proper syntax:

USE "os dz!kupci"

This saves me a bunch of time - just when I thought I'll have to rework the automatic naming :).
