You can increase the number of lines of the text block, so multiple.lines of 20 characters are possible. I normally use 16 to 20 lines.
Maybe I Wasn’t quite clear, but you’re only allowed 20 characters per line. So it only fills half the screen. If you open up an old algorithm you can see that they have more characters in the line, but if you try to edit them the limitation kicks in. No biggie though.
