Not true.  When a shell is opened, ^Y is turned off.  The reason is
obvious...ugly things would happen if you did a ^Y in csh and VMS trapped
it.  If you do a "suspend", a simple

	SET CONTROL=Y

will enable ^Y for the duration of the DCL.  (Today's handy hint: define
"Y" as a logical name to do this).  Of course, if you don't enable ^Y you
can always ^O, drum your fingertips merrily on the tabletop for 30 seconds
or so, and then continue on when you get your prompt back.  As ugly as the
^O solution is, it's probably easier (and quicker) than logging on somewhere
else, locating your PID, and stopping it.
