NAME

   linsert - Insert elements into a list

SYNOPSIS

   linsert list index element ?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.  The interpretation of the index value is 
   the same as for the  command  string  index,  supporting  simple  index 
   arithmetic and indices relative to the end of the 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]
