	hmm, I seem to remember seeing file formats, data representations, and
lots of other goodies in my manual set....and at least the vms guides tell you
exactly what the program will do (ever try to actually figure out how to use
badsect or bad144 from their manual pages????)
	And lets face it, to really experiment you have to read the code
anyway for both systems :-)

	funny, I know of now dcl shells for unix, but I know of two vms
'shells' which emulate unix (including pipes, redirection...) and only
one of the two is from dec (the other is public domain) and at least two
full unix emulators (more than just the shell, libraries, system calls, etc)
for vms - has anyone yet seen a vms emulator for unix ???  :-)
