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

Tcl																       lappend(1T)

lrange(1T)						       Tcl Built-In Commands							lrange(1T)

__________________________________________________________________________________________________________________________________________________

NAME

       lrange - Return one or more adjacent elements from a list

SYNOPSIS

       lrange list first last
_________________________________________________________________

DESCRIPTION

       List  must  be  a valid Tcl list.  This command will return a new list consisting of elements first through last, inclusive.  First or last
       may be end (or any abbreviation of it) to refer to the last element of the list.  If first is less than zero, it is treated as if  it  were
       zero.   If  last is greater than or equal to the number of elements in the list, then it is treated as if it were end.  If first is greater
       than last then an empty string is returned.  Note: ``lrange list first first'' does not always produce the same	result	as  ``lindex  list
       first''	(although  it  often does for simple fields that aren't enclosed in braces); it does, however, produce exactly the same results as
       ``list [lindex list first]''

EXAMPLES

       Selecting the first two elements:
	      % lrange {a b c d e} 0 1
	      a b

       Selecting the last three elements:
	      % lrange {a b c d e} end-2 end
	      c d e

       Selecting everything except the first and last element:
	      % lrange {a b c d e} 1 end-1
	      b c d

       Selecting a single element with lrange is not the same as doing so with lindex:
	      % set var {some {elements to} select}
	      some {elements to} select
	      % lindex $var 1
	      elements to
	      % lrange $var 1 1
	      {elements to}
