Prentice, I do not think the Fortran standard limits the size of one dimension in an array, although you can have only 7 dimensions. This to me must be a limit internal to their compiler. There may be an environmental variable to reset. I would try another Fortran (maybe gfortran) to see if you get similar behavior or find another (different) limit. Limits should really be operating system imposed based on the size of the address space. Intel says as much on the website describing their compiler.
