Man! You guys waste no time 🙂 I’m really glad that it’s out. I have the Fortran 2008 edition and I’ve put off buying the 2018 version in the hopes that 2023 would come out soon. EDIT: It’s on Amazon. ---

Great! I’ve been a happy customer since learning Fortran as an undergrad via “Effective Fortran 77”. Just ordered a copy to ship over from the UK… ---

Ordered it, too. Seems to not be available in Germany yet, so I guess I have to wait until March. ☹ ---

Sorry to hear that; I’m investigating. In the meantime, [amazon.co.uk](https://amazon.co.uk) is claiming that it will deliver to Germany by 23 December. Mike ---

My local (Dutch) bookshop claims to be able to deliver in 4 or 5 days. Odd, but I have not yet ordered it, so I do not know if their claim is correct. ---

I got the book and read a couple of chapters. I am very satisfied with it. One question: In Figure 2.4, there is an allocatable vector of the type `one`: ```auto type(one), allocatable :: alloc(:) ``` Where ```auto type one integer :: comp end type one ``` The authors talk about `alloc % comp`. But if alloc is a vector, can we refer to the comp like that? Even in the text? Should it be something like `alloc(:) % comp`? ---

The book is correct. For example, the following code compiles and runs with gfortran, ifort, and g95 ```auto implicit none integer, parameter :: n = 3 type one integer :: comp end type one type(one), allocatable :: alloc(:) integer :: i allocate (alloc(n)) do i=1,n alloc(i)%comp = i**2 end do print*,alloc%comp end ``` and gives output `1 4 9`.
