linsert(n) Tcl Built-In Commands linsert(n) 





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]
