X-Midas Users Take Note:
Think of data addressing as one-based in X-Midas (follows Fortran standards) and zero-based in NeXtMidas (follows C/C++/Java standards). Some people like to think of the difference in terms of using an index value in X-Midas and using an offset value in NeXtMidas, though this terminology is far from universal (officially Java and Fortran both use the term "index" but with different definitions).
