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
