Hi Ryan;
In addition to what Roland said, there is also the Get/SetProfileInt() methods as well to assist you in interoperating with INI files. The key thing to remember when creating INI files with newer PB & O/S versions is that they are expected to be Unicode. So if your using Notepad for example, make sure when you do a SaveAs that you select the Unicode format in the save dialog.
For a good example of INI file use, have a look at my example OrderEntry application built from the STD Foundation Class framework. The entire PB framework is INI file driven. The INI approach works for native PB, .Net, Web & Mobile deployed applications from PowerBuilder.
FYI: OrderEntry
