[Info-vax] Correct way to dismount shadowed volume set as late as possible?

[Dave Froble]

Not that Phillip will ever be convinced by anyone else, but, it's a slow 
day, so why not?

Just measured a VT-520 display.  Diagonal size is 12 inches.  I'll let 
you metric types do your own conversion.  That is about 10 inches wide 
by 7.5 inches in height.  I think that comes out to 75 sq inches of area.

The 19 inch diagonal flat screen LED monitor I'm using is 15 x 12, or 
180 sq inches area.  Do you think that 2.25 to 1 ratio might allow 
better visibility and usefulness?  I think so.

The display is amber on black.  Not too many options.  The 19 inch 
monitor has many color options.  Myself, I use black foreground on white 
background.  You can use whatever you like, even amber on black.

A VT-420 or VT-520 terminal allows multiple "windows", called sessions. 
The terminal emulator can have multiple sessions also, and usually more 
than any VT terminal.  Isn't "more" better?

However, pulling up a calculator over the current VT terminal "window" 
is a bit more work than what WEENDOZE provides with no extra work.  That 
can be helpful.

A VT terminal does allow cut-n-paste, but it's a bit more work (and 
memory of how to do) then what I can do with my terminal emulator on 
WEENDOZE.

Of course, if I run EDT in a terminal emulator window I can still do 
just about everything I can do on a VT terminal.

I got no problems with that ....

And the possibilities are endless ....

I'm not a big fan of "cut-n-paste" when working on VMS programs.  EDT 
does allow multiple buffers, and cut and paste between buffers doesn't 
possibly "mess" with your text, formatting, and such.

And now for a big difference.  As far as I know, a VT terminal will not 
show 2 sessions on the display at the same time.  Note, I may be wrong 
with this claim, don't think so.  On the WEENDOZE "user interface 
appliance" I can have 2 windows, side by side, and compare two files. 
That is a big winner for me.
