NAME

   join - Create a string by joining together list elements

SYNOPSIS

   join list ?joinString?
______________________________________________________________________________

DESCRIPTION

   The  list  argument must be a valid Tcl list.  This command returns the
   string formed by joining all of the  elements  of  list  together  with
   joinString  separating  each adjacent pair of elements.  The joinString
   argument defaults to a space character.

EXAMPLES

   Making a comma-separated list:
          set data {1 2 3 4 5}
          join $data ", "
                1, 2, 3, 4, 5

   Using join to flatten a list by a single level:
          set data {1 {2 3} 4 {5 {6 7} 8}}
          join $data
                1 2 3 4 5 {6 7} 8
