The simple answer is that something like that is hard/impossible to do in C. An array is simply a pointer to some memory. There's no really *good* way to tell how large that chunk of memory is. If the C compiler is using certian kind of heap structures you could determine the size of the chunk of memory from the heap structure. BUT even if you could do that, if you incremented the pointer so that it was inside another chunk of memory, it would look at the size of *that* chunk, and the bounds check would be OK. The the pascal you used, arrays were really arrays, and carried around a size tag with them. You can do some sorts of bounds checking in C with some tools, but it *CANNOT* catch everything or even many cases. I was using STL recently and i was surperised that vectors don't have bounds checking. I would think it would be in there as a switch, at least. dave
