My suggestion is to save the level data into an appvar and then read the appvar from your main program. This increases your maximum code size and makes it really easy for you to add new levels and allows for users to eventually make their own level packs.
If you absolutely need to hardcode it into the program though, you can use the new >Hex command to create an ascii string, save it to the OS Str1 or something, and then use [2nd][Rcl] to import it into your source.
