_________________________________________________________________

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
