Hello,
until now I have used fortran77, but now I'm trying to
work with fortran90.
As a beginners with this standard I have some difficulties on
understanding the real nature of the pointers.
In C a pointer refer to the memory address af a varibale. So you have
two operators & and *, the first assign to a variable (the pointer) the
address and the second gives access to the value referred to by the
pointers. If I have undestand well, in fortran 90 the pointers don't
work in this way. If I write X => Y this is a sort of 'symbolic link',
so that I can use X instead of Y. What is the difference, if any,
between the two situations?
May be they are the same but I haven't the notions to understand it.
