Hi Jens,
**++++ Error in CL-POSTGRES::WRITE-ASCII-STRING: Unknown LOOP keyword in (... CHARACTER :ACROSS STRING :DO (WRITE-BYTE (CHAR-CODE CHAR) STREAM)). Maybe missing OF-TYPE loop keyword.
Indeed, I left out the :of-type -- in fact, I didn't even know there was such a thing. I pushed a patch which, unless I missed one, adds the :of-type to all type declarations in loops. Could you get the code from the repository and try again? You are probably the first one to try Postmodern on Lispworks, so I'm interested how it goes -- let me know if there are any more errors, and especially let me know if it works.
Cheers, Marijn
