I broke your lines for you.

When you post to a newsgroup, you must limit the length
of your lines.


Attila Forth seems much more powerful than ANS Forth.


MAP( xt elem -- )

Destructively map the word xt over the elements of the list
from elem, replacing each element with the result of executing
xt with the previous value on the top of the stack.


FOLDR( xt acc elem -- fac )"fold are"

Fold the word xt over the elements of the list from right to
left. Theword being folded is expected to have a stack picture
( accbefore v -- accafter ) and is passed the accumulated
value (initially ac) and each element's value.


FOLDL( xt acc elem -- fac )"fold el"

Fold the word xt over the elements of the list from left to
right. Theword being folded is expected to have a stack
picture ( accbefore v -- accafter ) and is passed the
accumulated value (initially ac) and each element's value.
