But some stuff is more compiler dependant, than Ada is (although there can be differences between Ada compilers, however it is my understanding that those are clearly documented). > > Ada 95 on the other hand gives you the ability to specify the layout of > > structures with greater precision (in general).

What I meant was that Ada gives a clearer view of such a structure which imo gives it an edge over C++. I've tried making low level structures with C++, and it's not nice. Coupled with large variations in compiler behaviour, means C++ isn't in my 5 most frequently used languages. Chris
