Sometimes it takes 10 years of real world implementation to realize something was a bad idea. Were there people that argued against operator overloads and advanced records I wonder? Those I’m 100% certain were good ideas and really make my life better. I'm even suspect of generics even though I use them often. I don’t use dynamic arrays but others here seem really attached to them. Even with all the language cruft at least FPC doesn’t force any of it on you like C# forces you to use classes for everything and denies you from allocating stuff on the stack. That’s where it crosses a very real line for me. You can still make procedural program and be totally oblivious to everything that happened in the last 20 years. :) Regards, Ryan Joseph ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
