you create the .txt file in your mirc directory (default is under c:\users\uname\AppData\Roaming\mIRC\test.txt) and then you can write and read with these:

Code:
write text.txt $var
$read(text.txt,n,$var)


Now you can manually put them in the text file and just read them in, or if you want to do it mostly from twitch chat you can use the write commands.

Have a look at this one, it's pretty good: https://github.com/crdx/trivia-mrc
