Here's a public wish that C= would provide the technical information
in Amiga Mail in electronic form, perhaphs after a delay to give
subscribers "first jump".  Good technical information that *everyone*
can have helps the machine.


"The path list is held as a BPTR in the CommandDir member of the
CommandLineInterface structure.  Although currrently documented as
the lock on the command directory, this is either zero or a BPTR
to a list of path elements, each consisting of:
	BPTR	NextPath	(BPTR to next in list)
	BPTR	PathLock	(BPTR to a lock on the directory)"

The lock on the currrent directory is *NOT* in the list, nor is
the C: lock.  I feel this is unfortunate, as there are real
reasons for wanting to play with the order of those two as well.
