I am thinking about writing my own shell for the PC and there
are some questions I have about the environmen COMMAND.COM
lives in.  Anybody out there know ...

	How does COMMAND.COM tell DOS where the handler for the
	EXEC function is?

	How is it possible that the word at offset 6 in the program
segment prefix is both part of a long jump call and the size of a the segment.

There were more but I've lost my notepad.  If somebody answers these
then maybe I'll dig up the rest.  Thanks in advance if you
know the answers and share them with me.
