NAME

       linsert - Insert elements into a list

SYNOPSIS

       linsert list index ?element element ...?
________________________________________________________________________________________________________________

DESCRIPTION

       This  command  produces  a  new  list from list by inserting all of the element arguments just before the
       index'th element of list.  Each element argument will become a separate element  of  the  new  list.   If
       index is less than or equal to zero, then the new elements are inserted at the beginning of the list, and
       if  index  is  greater or equal to the length of list, it is as if it was end.  As with string index, the
       index value supports both simple index arithmetic and end-relative indexing.

       Subject to the restrictions that indices must refer to locations inside the list and  that  the  elements
       will  always  be  inserted  in order, insertions are done so that when index is start-relative, the first
       element will be at that index in the resulting list, and when index is  end-relative,  the  last  element
       will be at that index in the resulting list.

EXAMPLE

       Putting  some  values into a list, first indexing from the start and then indexing from the end, and then
       chaining them together:

              set oldList {the fox jumps over the dog}
              set midList [linsert $oldList 1 quick]
              set newList [linsert $midList end-1 lazy]
              # The old lists still exist though...
              set newerList [linsert [linsert $oldList end-1 quick] 1 lazy]
