llength(3tcl)

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  dictionary  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
