Hi, I use a Intel Fortran Compiler Integration for Microsoft Visual Studio .NET 2003, Version 8.1.2790.2003

and I recive this error :

" forrtl: The requested operation cannot be performed on a file with a user-mapped section open.
forrtl: severe (38): error during write, unit 35, file for035.dat"

what can I do?

thank you

Luca, it would be fine to know following:

- Which version of Intel Visual Fortran you are using (it is reported e.g. when the compilation starts or you can find in Visual Studio under Tools - Options - Intel Fortran - Compilers).

- How you are opening the file (complete OPEN statement) and what you are expecting to write to it.

I am getting the same error (see http://software.intel.com/en-us/forums/showthread.php?t=60735), but it is probably too general and random, so there was no reply or suggestion. It even went so far that my console application caused the computer running the calculation to crash. I am not sure, but I think that the main problem was and is using the BACKSPACE statement.
