Hmm, as I said, it depends on what 'parseLink' does. However the lists
of characters (i.e. the chopped URLs) should be passed.
I tried this:
(client "picolisp.com" 80 "wiki/?home"
(make
(while (from "<a href=\"")
(link (till "<" T)) ) ) )
and get a list of strings.

This is not a good idea, because 'client' opens its own 'out' back to
the server. You need it inside of 'client', e.g.
(client "picolisp.com" 80 "wiki/?home"
(out NIL (echo)) )
BTW, this is the most basic call to see what 'client' does.

Hmm, this is also not a good idea. 'msg' prints to stderr, so nothing
gets printed into "hh.html".
Besides this, the (out "+xxx) is OK, however quite some overhead because
it is re-opened and closed all the time. Better would be
(client ..
(out "hh.html"
(while (from "...
(println (till "<")) ..
This will print the lists to the file.

Sorry to hear that! But I think we are getting closer ;)
