The issue is that LOOP-FINISH terminates iteration as a whole, instead of terminating only the current iteration and continuing from the next one. There's no equivalent of "continue" in standard CL - you'll either need an explicit short-form LOOP like (loop (tagbody :start ...)) or to rewrite the loop to use IF instead, as detailed in another reply. And, as mentioned, clo-devel is a wrong place to ask. :D ~phoe On 24.03.2021 22:15, Erik Huelsmann wrote: > Hi Marco, > > Did you intend to send your mail to pro@ -- this being the list to > discuss the direction the common-lisp.net service takes? > > Anyway, you may be looking for "loop-finish" > http://www.lispworks.com/documentation/HyperSpec/Body/m_loop_f.htm : > The loop-finish macro can be used lexically within an extended loop > form to terminate that form ``normally.'' > > Regards, > > Erik. > > On Wed, Mar 24, 2021 at 9:27 PM Marco Antoniotti > <[email protected]> wrote: >> Hi >> >> I was porting some code to CL which has many >> >> for .. { >> if ... continue; >> ... >> } >> >> What is the best way to render this with LOOP?
