System V questions

[NRL::HERMAN]

	I have two questions about using Version V (3.2) Unix.

 i) How can I get the prompt to show me the current directory.

 ii) Is there something available in System V which is equivalent to the 
	'alias' command available in BSD UNIX.  That is, can one define 
	symbols in a way similar to the way #define defines symbols in C.
