The number of simple variables in a program is generally modest, and they tend to be local rather than global. Arrays and such tend to require address arithmetic anyway, so there is little penalty in simply parking a pointer to them in an anonymous simple variable. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
