NAME

       join - Create a string by joining together list elements

SYNOPSIS

       join list ?joinString?
_________________________________________________________________

DESCRIPTION

       The  list  argument  must be a valid Tcl list.  This command returns the string formed by joining all of the elements of list together with
       joinString separating each adjacent pair of elements.  The joinString argument defaults to a space character.

EXAMPLES

       Making a comma-separated list:
	      set data {1 2 3 4 5}
	      join $data ", "
		   => 1, 2, 3, 4, 5

       Using join to flatten a list by a single level:
	      set data {1 {2 3} 4 {5 {6 7} 8}}
	      join $data
		   => 1 2 3 4 5 {6 7} 8

NAME

       lappend - Append list elements onto a variable

SYNOPSIS

       lappend varName ?value value value ...?
_________________________________________________________________

DESCRIPTION

       This  command  treats  the  variable given by varName as a list and appends each of the value arguments to that list as a separate element,
       with spaces between elements.  If varName doesn't exist, it is created as a list with elements given by the value  arguments.   Lappend	is
       similar	to append except that the values are appended as list elements rather than raw text.  This command provides a relatively efficient
       way to build up large lists.  For example, ``lappend a $b'' is much more efficient than ``set a [concat $a [list $b]]'' when $a is long.

EXAMPLE

       Using lappend to build up a list of numbers.
	      % set var 1
	      1
	      % lappend var 2
	      1 2
	      % lappend var 3 4 5
	      1 2 3 4 5
