I'd been trying to open it all over the place, in case it was a locational issue. Tried running those three from the planning screen, and got:
Code:
File "<string>", line 1: end of line expected.
jump label done
^
Same if I do it in the middle of the working day. Naturally, it changes what text is in the second line to match what I'm typing, but the carat always points at 'label'.
From the title screen (or while the developer menu is open):
Code:
SyntaxError: invalid syntax
