linsert(3tcl)
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]
