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. 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.
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]
