Well, at the risk of stating the obvious, why not use CLOS (Common Lisp Object System)? It is in the new CL standard, after all. A good CLOS implementation that runs on most CL platforms can be obtained via anonymous FTP from arisia.xerox.com, in subdirectory pcl. PCL is a relatively large and robust subset of CLOS, from my understanding. Or did you mean something else by "frame language"? - Marty Hall ------------------------------------------------------ hall@aplcen.apl.jhu.edu, hall%aplcen@jhunix.bitnet, ..uunet!aplcen!hall Artificial Intelligence Lab, AAI Corp, PO Box 126, Hunt Valley, MD 21030
