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
