The way I read the original article is that there ]are problems with referring to variables which are unassigned or which ]go out of scope (dangling pointers and the like). Higher-level languages ]don't have these problems... If that's what you meant, then I agree, assuming we are using the same definition of "higher-level" (but I don't think we are). When you say ]...the fact that assignment is non-existent (or kept ]to a minimum), I suspect that you have a mental linkage between the term "higher-level" and the term "applicative". You aren't alone in this, but I think there are two distinct concepts there, and they should be kept seperate. I _will_ agree with ]the fact that the languages are garbage-collected and ]heap-safe, make them "better" in this sense. since if you don't have automatic storage managment, then you are extremely limited in the types of first-class objects you can have. In fact, I am tempted to define "higher-level" in terms of the built-in data types the language suports. -- David Gudeman Department of Computer Science The University of Arizona gudeman@cs.arizona.edu Tucson, AZ 85721 noao!arizona!gudeman
