<p><b>Notes:</b>
The DOS Requester replaces the NetWare Shell (ANETx, NETx) on
NetWare LAN's as of the release of Advanced NetWare 4.0 (1993). It
is backward compatible with NetWare 2.1x through 3.11 servers as
well. Note that there was a NetWare 4.0 in the early 1980's, which
can cause confusion..
This call is used as the installation check by VLM.EXE, which is the
loader for all the modules of the DOS Requester.
.VLMs are standard old .EXE format executables whose normal entry point
merely terminates to prevent loading from the command line (Novell's
VLMs all return errorlevel 6). The real entry point is found by
looking at the VLM header at the beginning of the load image
