Is there any intrinsic statement in fortran90 to deallocate all allocatable matrices at once? Something like Deallocate (ALL).... Or i have to deallocate them one by one?

On Windows, when an application ends, the effect is the same.
This applies to memory obtained by way of ALLOCATE in Fortran malloc/new in C/C++ (assuming non-overloaded malloc/new). On C++, the dtor would be bypassed, but the bulk memory would be returned.
You should get into the habbit of matching DEALLOCATEs with ALLOCATEs.

Also, if you declare ALLOCATABLE arrays local to a procedure, and have not marked them SAVE, they will be automatically deallocated when the procedure returns.

I'm using QuickWin features and i want to open input files consecutively from my File ---> Open menu that i have created in the QuickWin application. When i load the first file the program runs until the end... When I load the second file it says "fortrtl (151) severe: Allocatable array is already allocated" and stops! How can i avoid this without closing my QuickWin application?
PS. I haven't marked as "save" the allocatable arrays inside my procedures...
