The LINELENGTH command returns the length of its arguments, all concatenated and separated by one space character from one another.
var := LINELENGTH arg1 ... argn
// returns 5 (3 arguments of 1 character each, plus 2 // whitespace characters, one separating "a" from "b", the // other separating "b" from "c" #a := linelength a b c // also returns 5 (3 arguments of 1 character each, plus 2 // whitespace characters, one separating "a" from "b", the // other separating "b" from "c" #a := linelength a b c // returns 5 - due to quoting, the first argument now is "a b c" #a := linelength 'a b c' // returns 6 - there is exactly one quoted argument, and under // quotes, each whitespace character counts #a := linelength 'a b c'
Compare this with the LENGTH command returning the length of its first argument only:
// returns 5 (length of "hello") #len := linelength hello world
// returns 11 (length of "hello", plus one delimiting character, // plus length of "world") #len := linelength hello world
