[net.bugs.4bsd] csh foreach variable can't have digit

pmontgom@sdcsmb.UUCP (Peter Montgomery) (10/29/85)

# csh does not allow the variable name in a foreach to contain a digit.
# For example,

foreach a2z (a b c d e f g h i j k l m n o p q r s t u v w x y z)
	echo $a2z
end

# produces "foreach: Invalid variable."
# It works if both occurrences of "a2z" are changed to "atoz".

# The problem exists on a VAX 11/750, a VAX 11/780,
# and a SUN Workstation, all running 4.2bsd.

# Problem reported by Peter Montgomery of System Development
# Corporation in October, 1985.

Don't blame me for the crowded freeways - I don't drive.
