Hope this helps.
Not really, that's the documentation that I'm confused about. It starts out with the statement that strings will be printed verbatim. My variables are strings, but they aren't printed. I understand from Jens' response that I can get the function to work by wrapping my variables in (str ...), but I don't understand why that's necessary. The documentation of str suggests it's not necessary for strings: A form which is neither a string nor a keyword nor a list beginning with a keyword will be left as is except for the following substitutions: My variables are already strings: * (multiple-value-bind (records fields) (select [genus] [species] :from "specimens" :where [< [specimen_id] 4]) (loop for rec in records do (loop for label in fields for val in rec do (fresh-line) (princ (stringp label)) (princ (stringp val))))) TT TT TT TT TT TT NIL * Can someone explain why my variables aren't being treated as strings within with-html-output? The definition of (str ...) continues: Forms that look like (str form1 form*) will be substituted with (let ((result form1)) (when result (princ result s))). I'm new to Lisp (as must be clear by now!): what is the difference between (princ form1) and (let ((result form1)) (princ result)) Thanks for your help, Tyler
