>1)  Which Forth "standard" should I adhere to?

	Forth-79 is still around but pretty dormant generally. The
Forth-79 implementation MVP-Forth is a nice intro to Forth on the
Amiga, but not very useful for interfacing the operating system.

	A4TH1.5 is a Laxen & Perry Forth-83 "clone" in 32-bits for
Amiga, and it's PD and downloadable everywhere.

	There is NO true Forth-83 implementation on the Amiga, since
Forth-83 says 16 bits, and all decent Amiga Forths are 32-bits. 

	The ANSI Standard Forth is on the way, give it another 18
months is my unofficial guess.

>2)  Is J-Forth for the Amiga a worthy product (it will be my $150 bucks)?

	Yes. So is MultiForth. JForth is my fave, though. A complete Amiga
development environment for one third the price of a comparable C
environment.

>3)  Is Forth good for Amiga graphics (what else, sound perhaps)?

	It's good for whatever Amiga is good for. JForth has a lot of
neet "pre-fab" graphics stuff written you can play with.

>4)  Is there other literature you would recommend?

	_Threaded Interpretive Languages_, Loeliger, BYTE Books, 1981

	_Inside F83_, C.H. Ting, Offete Enterprises, 1985

	_Object Oriented Forth_, Dick Pountain
