Tcl Built-In Commands                                 llength(1T)





NAME
     llength - Count the number of elements in a list

SYNOPSIS
     llength list



DESCRIPTION
     Treats list as a list and returns a  decimal  string  giving
     the number of elements in it.


EXAMPLES
     The result is the number of elements:
          % llength {a b c d e}
          5
          % llength {a b c}
          3
          % llength {}
          0

     Elements are not guaranteed to be exactly words  in  a  dic-
     tionary sense of course, especially when quoting is used:
          % llength {a b {c d} e}
          4
          % llength {a b { } c d e}
          6

     An empty list is not necessarily an empty string:
          % set var { }; puts "[string length $var],[llength $var]"
          1,0
