Created attachment 156 [details] There it is Just what it says on the subject: as is right now, if someone types '.opt "+o"' or 'opt "~o"', nothing happens. People coming from other assemblers assume that this turns all optimisations on or off, so confusion ensues. So, the patch adds an error message when this happens. Also, some small additions to the manual, especially on missing directive descriptions.
Thanks for the patch! :-)
