I have no idea what he thinks now. :-) But in the quote, he states that he (or his company) suggested an option to turn off the checks and the customers said "No!" The other extreme is a language that does not have the checks, and when offered a "helper app" that might do _some_ of the checks, some users say "No!" Seems like Ada has a nice balance between those extremes. -- Wes Groleau http://freepages.rootsweb.com/~wgroleau
