Brad, I agree it's kind of ugly and I've never been a fan of code duplication. (Which reminds me - why do we need two copies of lookup(), one const and one not in CacheMemory?) I'll try the void * return suggestion, though I wouldn't hold my breath. I'm open to other suggestions as well, if anyone has any. I didn't get too creative here. - Lisa ----------------------------------------------------------- This is an automatically generated e-mail.
