Teletype Simulator REPL line break

Hello All,
I am new to developing for the teletype and have the docker installed and ran the make for the simulator. It successfully ran. How do I do a line break in the simulator (trying to test an ELSE)?

I am going to do a Pull Request shortly (after I test my work) that will allow an ELSE statement with PROB (I am sick of doing a IF <= 60 RND 100: to get an ELSE)
