    The article discusses the mysterious line in the source code of The Wizard's Castle, an 80s microcomputer BASIC game originally written for the Exidy Sorcerer platform. It reveals that the line contains machine code encoded as ASCII text, which is used to seed the random number generator (PRNG) by calling it through a POKE and USR function pair. This method of seeding the PRNG was likely not well-known or documented at the time.
