Which shell?  So far...

	V6 SHELL:  very restrictive
	PWB SHELL:  hairy outgrowth of V6 shell, developped for
		11's but now around on some VAX's
	BOURNE (V7) SHELL:  distributed with V7, available on almost
		all VAX's.  Mostly compatible between each machine.
	BOURNE (SIII) SHELL:  Modified above (hopefully compatible)
		comes with SIII/V on VAX/PDP.  Also available for
		4.x BSD (I think).
	CSH:  Berekeley wierd thing, comes with 4.x BSD.  Runs on
		other unix's to the extent of the kernels ability
		to support it.  Uses special BSD specific features.

Going between different implementations of the same shell is easy
(we even switched from the V7 to SIII Bourne shell without any
pain).  It is the programs that it is likely to call that are going
to cause you problems.  Does your /bin and /usr/bin programs function
the same way between machines?  Same options?
