LINELENGTH

The LINELENGTH command returns the length of its arguments, all concatenated and separated by one space character from one another.

var := LINELENGTH arg1 ... argn

The following example 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

This 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

This also also returns 5 - due to quoting, there is only one argument with the value of "a b c"

#a := linelength 'a b c'

This 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 := length hello world

// returns 11 (length of "hello", plus one delimiting character,
// plus length of "world")
#len := linelength hello world
