Hi,
the definition of the structure is wrong. Try this instead...
global constant
dwOSVersionInfoSize =3D allot( DWord ),=20
dwMajorVersion =3D allot( DWord ),=20
dwMinorVersion =3D allot( DWord ),=20
dwBuildNumber =3D allot( DWord ),=20
dwPlatformId =3D allot( DWord ),
szCSDVersion =3D allot( 128 ),
SIZEOF_OSVERSION =3D allotted_size()=20
The last field is supposed to be a 128 character array. You had =
defined it as a long pointer to a zero-terminated string (Lpsz). This =
would cause the SIZEOF_OSVERSION to be wrong, and the function won't =
work if that's wrong.
