Prints 39-egnufeB in Befunge-93, along with maintaining the other outputs in the other languages.
Next answer cannot exceed 287 bytes.
Will work in MTFI, and input must be given for PyFunge. #Hexdump

Befunge-93 does not know what ; is (in Befunge-98, it skips commands until the next ;), so it ignores it. Allowing us to distinguish the two versions of Befunge.
