Glen,

I'm sending the vddriver stuff back to you as a VMS SHARE package.  I've got
it to load and connect under FT4.  However, where to go from there, I'm at
a loss (ie. It's up to you ;-)).

Included in this is a MAKE.COM that compiles both ASNVDM6 and VDDRIVERALPHA
and links them.  This is taken from our standard Make environment here.

Here is what I fixed:

	1) Add the macro DRIVER_DATA (out of LIB.MLB) at the start of
	   the data section (DPT, DDT, etc).

	2) Add the macro DRIVER_CODE (again out of LIB.MLB) at the start
	   of the FDT code.

	3) Changed all references off of AP to IRP$L_QIO_Pn(R3) since you
	   are no longer passed an AP.  Instead, the P1 thru P6 parameters
	   are stored in the IRP.

	4) Move UCBTBL from the bottom of the file up to the data section
	   under the control of DRIVER_DATA.  Removed the reference to
	   PSECT $$$103d.

	5) Substantially changed the .OPT file.  The new options file is
	   now known as VDDRIVER.ALPHA_OPT.  You were missing a lot of stuff
	   about collecting the EXE$ stuff together to allow for slicing.

About the changes to the options file.  You may want to send mail to
Gerard Newman (gkn@tgv.com) who can explain the linker options better than I.
I'm still learning why they are needed and will probably mess up explaining
it correctly.

You will probably notice that ASNVDM6 fails to link properly using Make.Com.
However, if you issue the same command from the command line it works, don't
know why.

If there is anything else I can help with, let me know.  Sorry for taking so
long at this, but with InterOp and the Alpha announcement, I've been pretty
busy.
