1. Eu's good design

Hello there, Might be worth mentioning a few good points too... 1. Namespaces (quite versatile) 2. Ability to call virtual functions 3. Sequences I've heard that there are two kinds of programmers, those that like sequences and those that dont, and for the same reasons with different motivations. Sequences are both versatile and problematic. Depending on which you like/dislike about sequences decides whether you like or dislike Eu. If people spent more time building libraries then argueing about the problems they'd have more accomplished also Take care for now, Al

Anyways, I meant 'emulated' in the sense that its not builtin to the language. jbrown -- Outlook Users, please don't put my email address in your address book.

Hmm .. this can be done even more easily in C or asm. Euphoria isn't doing anything new here. Other high level languages may have something similar to this, and also might support virtual functions natively (i.e. if Euphoria had native support we could have virtual functions in Euphoria). jbrown -- /"\ ASCII ribbon | http://www.geocities.com/jbrown1050/ \ / campain against | Linux User:190064 X HTML in e-mail and | Linux Machine:84163 /*\ news, and unneeded MIME | http://verify.stanford.edu/evote.html
