Where can I find a good reference for FORMAT directives? I've looked on
google and can't find anything good. I'm trying to figure out what ~,5t
should mean. I've tried some examples and it doesn't seem to be
different from ~5t.

Slightly off-topic here, but if you are going any further, and starting
to use the pretty printer format directives, be careful if you are
using clisp (of clisp.cons.org) because it's pretty printer is not
completely conformant to the standard. Specifically,
pprint-logical-block (and associated pprint-newline, pprint-indent,
etc), or its ~<...~:> format directive (including : and @ modifiers),
when used with *pprint-miser-width*, *pprint-right-margin* and a few
other "flags", seem to show patchy standards coverage. I think ~T works
fine, but there might be a few other ones that would confuse newbies
like us if they were buggy (it was a while ago now, but I think there
were weird outputs from ~i as well). I wouldn't try any formatting that
is too fancy in clisp. For fancy formatting, I use SBCL, but clisp has
otherwise been very good to me.
Took me a while to figure that out, and now I'm itching to "port"
SBCL's pprint.lisp into clisp. Might get around to that one day. Right
now, it looks like a formidable task for me. At least I learnt a bit
about the pretty printer.
Thanks for the heads up. Installing SBCL as we speak on my new mac mini.

Though if you're looking for FORMAT you might do better to look at:

Just so we're clear on this ... thinking of your girlfriend makes you
fixate on the LOOP macro? :P
Your book (I own a copy) was the first place I looked. I also look on
gigamonkeys since it's searchable. I still couldn't find an explanation
of ~,5t which was used on the second to last page in the spam filter
chapter to format analyze-results.

In this case, the actual directive is ~T, the ,5 is a parameter to
that directive. There's information about it at
http://www.lisp.org/HyperSpec/Body/sec_22-3-6-1.html .
The best way I've come up with for looking up format directives is
just clicking through each of the subsections at the bottom of
http://www.lisp.org/HyperSpec/Body/sec_22-3.html until I find what I'm
looking for.

Yeah, I guess I decided to punt on the tabular output directives.
Well, there's always the Hyperspec. Basically ~T means "tab", but the
parameters affect it in slightly complex ways that I'll leave to the
Hyperspec to explain.

Graham's _ANSI CL_ has a good quickref in the back, for basic
summaries. ~t is a bit more complex than the ref can explain, but at
least it says basically what it is.
You might search under "tilde t" at http://lispdoc.com/ .
CLtL2's page is a bit easy to search, but you shouldn't seriously trust
it when it comes to details...
