When using the foundation class _error object FoxPro assigns the following to the property lserver=INLIST(_VFP.StartMode,1,2,3,5).

When I look in help for _VFP system variable it says that allowed values are 0-4.

Value Description
0 A development version of Visual FoxPro was started in an
interactive session.
1 Visual FoxPro was started as an application object. For example, the following command creates an instance of Visual FoxPro as an application object:
oMyObject = CREATEOBJECT('VisualFoxPro.Application')
2 Visual FoxPro was started as an out-of-process .exe automation server.
3 Visual FoxPro was started as an in-process .dll automation server.
4 Visual FoxPro was started as a distributable .app or .exe file.

Can anyone tell me why the base class permits looking for a value of 5? Am I not understanding this correctly?
