Standard vs. Professional compiler

[wasif1]

1) What is the main difference between the Standard and Professional versions of Fortran 9.1? Is there a difference in the virtual memory size available to a program developed in one or the other?

The reason why I'm asking is because we developed a program using large dynamic (allocatable) arrays, using the trial Standard version, and the program fails to allocate some of my arrays when the total virtual memory accessed approaches the 2GB size. We're expecting to get the Professional version soon and would like to know if that'd help me solve this problem.

The ONLY difference is that the Professional Edition also includes the IMSL Numerical and Statistics Libraries from Visual Numerics. The compiler (and everything else) is the same.

2GB is the limit on 32-bit Windows. To exceed that, you need:

1) A system based on a processor with extensions, sich as Intel processors with Intel EM64T
2) One of the "x64" editions of Windows XP or Windows Server 2003
3) Use of the compiler "for Intel EM64T-based applications"
4) Microsoft Visual Studio 2005 or the Microsoft Platform SDK
