linsert - Insert elements into a list
linsert list index element ?element element ...?
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. If index has the
value end, or if it is greater than or equal to the number of
elements in the list, then the new elements are appended to the list.
end-integer refers to the last element in the list minus the
specified integer offset.
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]
