Array to string in TCL

How can I convert a known array in to string in TCL? an array might have values such as root_user_appversion 10.1.3.20 and/or I just want to take out the last values out of it which 10.1.3.20 .

I think you want 

join [dict values [array get the_array]]

Which takes a list of alternating key / value items, filters out the value items, and joins them into a string.

Note that values with spaces will be munged: in that case you're better off with just dict values [array get the_array].

You can transform the array in list:

set my_list [array get my_array]

puts "last element: [lindex $my_list [expr {[llength $my_list] -1}] ]"

After that, you can easily convert your list in string with join:

set my_string [join $my_list " "]
