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.

NAME

       lreplace - Replace elements in a list with new elements

SYNOPSIS

       lreplace list first last ?element element ...?
_________________________________________________________________

DESCRIPTION

       lreplace  returns a new list formed by replacing one or more elements of list with the element arguments.  first and last specify the first
       and last index of the range of elements to replace.  0 refers to the first element of the list, and end (or any abbreviation of it) may	be
       used to refer to the last element of the list.  If list is empty, then first and last are ignored.

       If  first  is  less  than  zero, it is considered to refer to the first element of the list.  For non-empty lists, the element indicated by
       first must exist.

       If last is less than zero but greater than first, then any specified elements will be prepended to the list.  If last is  less  than  first
       then no elements are deleted; the new elements are simply inserted before first.

       The  element  arguments specify zero or more new arguments to be added to the list in place of those that were deleted.	Each element argu-
       ment will become a separate element of the list.  If no element arguments are specified, then the elements between first and last are  sim-
       ply deleted.  If list is empty, any element arguments are added to the end of the list.
