I'm not a API guru :) but let me ask you a little question: at what VFP excel? Table manipulation of course. So I go for a parameter table unless I want to give the user easy access to the parameters. In that case, I go for a INI file.

>Of course you could write it to an .ini file. But if you do not already have an .ini file for your app, this is just another instance of creating a "table" to hold one value -- just a different sort of table.

>I have used .ini files to hold values in VFP, but it's just as simple and more controllable to use a .dbf parameter table (uh oh, now I'm going to hear from the API gurus).
