actually, when I think of putting 2 sequences together, I
think 'concatenating 2 sequences' which means putting them together into
one sequence.  For example:
----------
sequence string1, string2, string3

string1 = "string1"
string2 = "string2"
string3 = string1 & string2
----------
in the program above, we concatenated string1 and string2 so
string3 = "string1string2"

I'd call what we did in your program 'creating a sequence of 2 sequences'.
----------
sequence string1, string2, string3

string1 = "string1"
string2 = "string2"
string3 = {string1,string2}
----------
in the program above, we created a sequence of strings (which are sequences
of ASCII codes).

string3 = { "string1", "string2" }
        = {{115,116,114,105,110,103,49},{115,116,114,105,110,103,50}}

there are other ways to do the same thing (making sequences of
strings/sequences)
For example:
----------
sequence string1, string2, string3

string1 = "string1"
string2 = "string2"
string3 = {string1}&{string2}
----------
or
----------
string3 = append({string1},string2)
----------
or
----------
string3 = prepend({string2},string1)
----------
will all give the same results:

string3 = { "string1", "string2" }
        = {{115,116,114,105,110,103,49},{115,116,114,105,110,103,50}}

but be careful not to do this:

string3 = append(string1,string2)

because you'll get this:
instead of this:

Sometimes I still make mistakes like the last example and it just takes the
reference manual and a little trial & error to get the structure I'm
looking for.
