I think that :

the two last lines should be

symbol x = table["x"]; symbol y = table["y"];

You're right. Only, a symtab maps to expressions, not to symbols, so you will have to coerce it to a symbol, first. Thanks for pointing this out. -richy. -- Richard B. Kreckel <http://in.terlu.de/~kreckel/>
