Are there any pure interpreters of Scheme? AFAIK, all of them insist on reading at least one top-level form before executing anything, and all do at least some preprocessing on that form. There are languages like APL and Basic that have been implemented by pure interpreters. -- John Cowan http://www.ccil.org/~cowan [EMAIL PROTECTED] Be yourself.
