I have been experimenting with three different versions of EMACS
on my ST,  
one is called simply EMACS.PRG, one is called MG, and the third is
called microEMACS and comes as a part of the Gulam shell.

So far, I feel that I have not progressed very far on the learning curve.
because I can not make any of them do much more than some primitive
word processors.

(I have used and written about two powerful programmable editors, and
am looking for some of the same capabilities.)

I have a few questions that maybe someone can help me with, please :-) .
I know that I am revealing my ignorance here, but that is exactly
what it is, ignorance.

	How can I read a file into an existing buffer?
		(This is what VI users do by typing
		the command ".r file".)

	How do I change in lines with "exp1", all instance of "exp2"
		to "text3".  (This is what VI users by typing
		the command   "1,$ g/exp1/ s/exp2/text3/". )

	How do I define a macro when starting the editor?

	Can I define a macros from a text file after the editor
		is running?

Thanks!
