The LENGTH command returns the length in characters of its first argument:
var := LENGTH string
Note that any surplus arguments are ignored. See LINELENGTH 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'
