I did somthing like that in my Learning Chatbot Project. It basicly "tears up" each row to find the individual strings, using ¶ as a delimiter (or whatever they are called).

I think it just takes the output list's item (the onpe it found), and puts the seperated data into another list, seperated. Ex.
Output: 123¶55¶I AM AWESOME
...
.Script
..-..-.
Outputlist:
123
55
I AM AWESOME

Then it can use the data.

Oh. It basicly has a list (Wordlist or something) and sequentially reads that characters of the to-be-seperated line. If its a ¶, it adds a black line to wordlist, else, it puts the read character onto the last line. Sort of like a text editor, if the key just pressed was enter (analogous to the ¶), add a new line, else, put the keystroke (analogous to any character besides the ¶) on the line.

Yes, it is. Try this script.

add (join (Variable 1) (join (,) (join (Variable 2) [and so on...]))) to  [List v]

For adding to a line it seems like something like this would work? If I'm understanding what you're talking about.

if <item (1 v) of [List v] = []>
replace item (1 v) of [List v] with (Addition to row)
else
replace item (1 v) of [List v] with (join (item (1 v) of [List v]) (join (,) (Addition to row)))
end
