It's the "set many" line that is causing the screen to go blank.
Technically, it was a bug in the line calling the error function that was causing it to go blank, as I had omitted the second argument for the line number. I have now fixed that so that if you use "set many" with an odd number of arguments, it will now give you a helpful error message instead of a blank screen.
