GREAT CARL!
but smallest ????
let me remember.. oh!
this little script below tells me yes with blanks, but no with tabs.
and i had to put some 100 byte extra in.
but ok, you included docs to :)
Could use real masters hand of course.
and using list-supply to avoid calculate-loop is more a joke ;-)
but i like the function-field and the dual sheet/editor-mode
(edit 'formulas in editor and run :)
and for rim the self-saving? iam not shure if its a good feature.
Well, after being proud to compete, i have to withdraw.
when reading your source,
its like seeing a tower grow very precise and quick.
after that i know where the parts belong.
while i wasn't able to build something more useful from my.
adding functions yes, but design, clearness..
and of course i use your great language.
but, you do too, so thats equal? ;-)
iam not sure about using A0, Z5..words, there are not so many..
last thinking was about some sort of dialect, maybe
replacing pairs with access-functions?
how would you design the dialect?
OK, RebSheet2 below. store and do mail, as usual ;-)
oh, and load ReboCalc before. or answer security-questions..
RebSheet want's to check its size..
size.. size? oh, store rebsheet with itself and restart
%rebsheet2-2.r .. otherwise it adds the mail size..
or copy/paste only code. or.. late night here, sending..
