Subject: [geeks] SPARC OBP: how to execute machine code?
Message-ID: <202503030330.WAA23244@Stone.Rodents-Montreal.ORG>

I'm addressing the original desire a different way, now, but it did
prompt me to wonder: from Sun OBP, what do I need to do to jump to some
machine code sitting in RAM?  Surely there's _some_ way to do it, since
loading bootblocks off disk does it after loading, but I haven't found
my way through the twisty little maze of FORTH words, all different, to
figure out how that does it.

Anyone happen to know the incantation?

You could use the call word, or init-program, set-pc and then go.
