Identifiers (Names)

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.

Examples of identifiers

hello
this_is_a_most_unusually_long_name
IF
foO
bAr
HorseSense
var1
var2
_auto_
_

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
