[colorforth] Mulitply Step (*+)

["Roman Pavlyuk \(personal\)" <john@xxxxxxxxxxxxx>]

http://www.ultratechnology.com/mfp21.htm contains quite clear explanations
and examples (4x4 multiplication to start with)

I used it for 16.16 FP multiplication for F21-like processor implemented in
FPGA.

http://www.eforth.com.tw/academy/sutra/chapter14.htm describes multiply step
and division step instructions of Dr. Ting's processors. See also
http://www.eforth.com.tw/academy/chips/rtx/cmforth.htm ,
http://www.eforth.com.tw/academy/library/emptyvalley/cmforth.htm and nearby.

Roman

Could someone explain this word in a little more detail for me? I haven't
seen
any stack notation or comments anywhere for it. Right now my best guess is
that it's used for array indexing? Thanks.
