Hm, I see. Very strange, definition looks ok.
Have no amforth-4.2 installed jet, maybe do it next days.


PS:
In float.fth I found:

\ STACK MANIPULATION WORDS

\ DOESN'T WORK?
: f>r ( f -- , R: -- f )
     >r >r ;

\ DOESN'T WORK?
: fr> ( -- f, R: f -- )
     r> r> ;

..

This indeed won't work.
Use 2>r and 2r> instead, they are provided in core/words allready.
