It's probably still there too!
DG did such a good job of simulating 16 bit AOS in 32 bit AOS/VS with
call translation within the agent that it never really bothered rewritting
most of the CLI, but left it in 16 bit assembler.
Strangely enough, xyzzy was a very useful command for debugging and a safe
way of putting in a must fill this code in reminder.
Also, xyzzy was implemented somewhere outside the general parser,
as if you give it any arguments or switches it returns the
error
NOT A COMMAND OR MACRO
unlike all other builtins which will say UNKNOWN SWITCH or UNEXPECTED ARGUMENT.
