Character

SYS(3006) sets the Visual FoxPro Language ID (LangID), and then sets the Locale ID (LCID) based on the Language ID and the current value of the Sort ID.

Note
Using the DefOLELCID Property is the preferred method for setting a Locale ID for a form or the main Visual FoxPro window.

For additional information about Language, Locale, and Sort IDs, see the Microsoft Windows Software Development Kit documentation.
