An identifier (name) consists of a sequence of letters and digits. The
first character must be a letter. The underscore character
_
is considered
a letter. EDEN imposes no limit on the number of characters in a name,
but the implementation of the EDEN interpreter does (about 255 characters).
An EDEN keyword cannot be used as an identifier.

Upper- and lowercase letters are distinct, so
Count
and count
are different
identifiers. An identifier is a symbolic name of a
variable,
function
or other objects.
Examples of character sequences that cannot be used as identifiers:
012 a fool $sys auto 3var pay.due foo~bar .name if
