How to define temporary arryas at execution time?

I want to set up something like the NEW statement in C++, where I don't want to allocate permanent storage, but only according to the size of the problem at execution time.

Does Fortran allow me to define an array that does not exist at compilation time, where the size can be defined by user input?

Even in some versions of C++ the user has to commit himself at compilation time regarding the sizes of arrays.

Yes. Look at ALLOCATABLE arrays. If an ALLOCATABLE array is a local variable in a routine, and not given the SAVE attribute, it gets automatically deallocated on routine exit.
