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]
