Common problem with VMS: Many of its editors and other full-screen programs
use the "restrict scroll area" VT100 escape-sequence. Possible workarounds:
1. Tell VMS what size your screen is, for example "SET TERM/PAGE=40". VMS
   may still restrict the scroll area, but to lines 1 to 40, which is OK.
1a. However, the EDT editor is too brain-damaged to use a smaller or larger
   screen, so method 1. will fail. Suggestion: Use EVE (a.k.a. TPU) instead,
   and set it to use the EDT keypad. Works nearly as well as native EDT.
2. After you come back from the VAX, echo the escape sequence "ESC [ r" to
   the screen. This escape sequence will reset the "restricted scroll area"
   to the full extent of the screen, thereby undoing the damage.
I hope the Linux VC's support this escape sequence without parameters.

Now, if someone could explain to me how to get my new 200MB IDE disk to work
right, so I can finally install Linux on my machine at home ... and no
pro/con VMS flame wars please.

My opinion. This is not SLAC, Stanford U, or the US DoE speaking. Just me.
