linsert(1T) Tcl Built-In Commands linsert(1T)__________________________________________________________________________________________________________________________________________________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 ele-
ment 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.
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]
