The reason for this is that either the LOGIN.COM file in ETC: or the
CSHELL.COM/SHELL.COM files in BIN: do a 
$  set nocontrol=y
In order that things like vi and others which use ctrl-Y as a command
character can function contentedly.  The way around this is to say

$set control=y

when you enter the VMS process.

I am not certain if this is process or terminal specific - that is, I do 
not recall with certainty whether or not exiting the DCL shell will
restore trhe correct state of ctrl-Y or if it is necessary to do so
explicitly.  I believe that exiting the VMS process does it.


Hope that's helpful.
