I am running a version of csh which comes with Convergent's CTIX
along with Sys V/3.0 and it does the same thing.  Put more simply,
if I have  a variable name with a digit in it, I cannot expand it
if I enclose the variable name in parentheses:

% set xy1z=asdf
% echo $xy1z
asdf
% echo ${xy1z}
Variable syntax.

I would call this a bug in CTIX, because the documention on csh reads:

$name
${name}
	Are replaced by the words of the value of variable
	name, each separated by a blank.  Braces insulate
	name from following characters which would otherwise
	be part of it.  Shell variables have names consisting of
	up to 20 letters and digits starting with a letter.  The
	underscore character is considered a letter.
