Hi Adam Deptula,
-D and -L parameters are reserved for the executable file:
-LFileName
Specify a resource file, including a path if necessary, other than the default, vfp*ENU.dll, so you can use Visual FoxPro in a language other than the current language specified by Windows.
-DFileName
Specify a runtime library file, such as vfp9r.dll.
For example,
test.exe -Daaa\vfp9r.dll -Lbbb\vfp9renu.dll
Best regards.
