I'm running GNU Emacs 18.52 under SunOS 3.5 on a network of Sun 3/xxx's, and
I have a couple of questions:

1)	Is it possible to cause a buffer to *not* recenter itself when
	it automatically scrolls?  I'd like certain buffers (but not every
	buffer) to scroll so that the line with the point on it ends up
	at the bottom of the screen instead of the middle.  I can do this
	manually via "(recenter -1)", but I'm talking about the automatic
	scrolling that occurs when the cursor is on the bottom line and
	I do a downward cursor motion, and the other automatic scrolling
	that occurs when an "(insert ...)" is done with text that would
	print beyond the bottom of the buffer.


2)	My next question involves the following Elisp code fragment:


		(setq my-variable "variable's value")
		(fset 'my-variable '(lambda () "variable's function return"))

	If I evaluate

		my-variable

	the result is "variable's value", and if I evaluate 

		(my-variable)

	the result is "variable's function return".


	This is well and good, but now for my question:

	Is there any way, through macros, obscure functions, or whatever,
	for me to do something to "my-variable" so that its function
	gets evaluated when I type its name without the enclosing
	parentheses?  In other words, I'd like to evaluate

		my-variable

	and have it perform the function in its function cell just as if
	I had evaluated

		(my-variable)

	It isn't absolutely necessary for my-variable's function cell to
	get evaluated ... actually, all I want is for *some* function of
	my choosing to be evaluated when my-variable is evaluated without
	any parentheses.

	The reason I want this is so I can change existing Elisp defvar
	elements to invoke a function of my choosing when they are
	evaluated, instead of returning their value cells.
	
Any suggestions?

Thanks in advance for your help.
