Hi

I've seen the constraction like

   (format t ··@<erred while invoking ~A on ···@:>" a1 a2)

more than once in code. However, I found nothing neither in 22.3.6.2
nor 22.3.6.3 of HyperSpec which could have thrown a light on it. Can a
conforming application rely on it? And what's the description of it's
doings?

Thanks in advance

Look in Sec. 22.3.5 "FORMAT Pretty Printer Options".

Thanks, How could I overlook it!

BTW, reading your PCL gave me a noticable change in my understanding
(or may be my attitude to them) of macros. Now I use them much more
frequently than I did before. Previously I gravitaded chiefly to
functions (or GF) and now I share my interest equally between them
(functions and macros). I think of macros now as one of the most
powerful methods of genralization (factorising?) the code and
frequently it is the only possible way.
