I think you are quite confused :) Use procedures, not macros. If you really want to use s-expressions, use alists and define accessor procedures, and be sure not to mutate literal values. You could use hash tables and records also. Or myriad other data structures. Read http://mitpress.mit.edu/sicp/, especially the chapters on data abstraction and state. But above all, don't take your data structure advice from anyone who mentions SQL :) Andy -- http://wingolog.org/
