	<code>~~<var>var</var> :=~~ LENGTH ~~<var>string</var>~~</code>		The <code>LENGTH</code> command returns the length in characters of its first argument:

	-> var = ~~'numberofcharacters'~~		<var>var</var> := LENGTH <var>string</var>

	~~Get the length of the string <var>string</var>~~. See <code>[[Programmer Guide/Command Reference/LINELENGTH\|LINELENGTH]]</code> for an alternative~~, which can retrieve~~ the length of ~~a line~~ including delimiters (e.g. whitespace).		Note that any surplus arguments are ignored. See <code>[[Programmer Guide/Command Reference/LINELENGTH\|LINELENGTH]]</code> for an alternative command retrieving the length of all arguments, including argument delimiters (e.g. whitespace).

			// returns 1 - the first argument is "a"
			#a := length a b c

			// returns 5 - due to quoting, the first argument now is "a b c"
			#a := length 'a b c'

			// returns 6 - under quotes, every whitespace character counts
			#a := length 'a b c'
