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
