The SYS(2019) function will return the full path and file name of the configuration file that Visual FoxPro actually used. If no configuration file was found, the function merely returns an empty string. What goes into the configuration file?

Essentially there are three categories of things that can be specified in the configuration file as follows: Special settings There are a number of settings that can ONLY be made in a configuration file.

F. 1 *** Set up any standard "Public" variables PUBLIC gcUserName, gcAppPath, gcDataPath STORE "" TO gcUserName, gcAppPath, gcDataPath *** Run Standard Path Set-up DO setpath WITH 1 As you can see, apart from setting up the basic VFP system environment and handling our own particular requirements, this 'one' command available in the configuration file has now been used to run a couple of other programs (CEE and our own SetPath procedure) so we get three for the price of one.
