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 SEE ALSO

concat - Join lists together SYNOPSIS
concat ?arg arg ...? _________________________________________________________________ DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args are supplied, the result is an empty string. EXAMPLES
Although concat will concatenate lists, flattening them in the process (so giving the following interactive session): % concat a b {c d e} {f {g h}} a b c d e f {g h} it will also concatenate things that are not lists, as can be seen from this session: % concat " a b {c " d " e} f" a b {c d e} f Note also that the concatenation does not remove spaces from the middle of values, as can be seen here: % concat "a b c" { d e f } a b c d e f (i.e., there are three spaces between each of the a, the b and the c).
