Interesting. I had not heard of this, nor seen any books describing it. (Or is the standard available by ftp somewhere?) Apparently the compiler houses are not rushing to implement it either. >For what it's worth, the easiest way I can think of to implement "modern" >Pascal would be to build it on top of GNAT. I'm not sure whether this >says more about Pascal Extended or about Ada. Even more interesting. Can you briefly describe how to build it on top of GNAT? (Pascal-ish _sets_ are a CS2 exercise to build on Ada 83.) Are there Pascal extended features that carry over easily into Ada?
