Intel has released its oneAPI toolkit, which includes full support for
Fortran 2018. Even better news, it's free if you don't mind "community
support". (If you want Priority Support, you can buy it.)

There are two Fortran compilers here. ifort is the next version of what
had been in Intel Parallel Studio XE, and is the one with the full
Fortran 2018 support. ifx is a new, LLVM-based compiler and is still
considered "beta".

As is usually the case, there may be divots in the F2018 support - these
should be reported to Intel. I have been trying the beta and it's very good.

Forgot to mention - the Fortran compiler is in the "HPC Toolkit". You
also need the "Base Toolkit" but can deselect all of the optional
components if you want.

A follow-up. In fact you do NOT need the Base Toolkit to use Intel
Fortran (or C++). MKL is in the Base Toolkit, but it can be installed
separately if desired.

I've downloaded and installed on a couple of development systems.

On the ifx front I've found it pretty good. It compiles and runs most
of the examples from our book. (4th edition)

I've hit internal compiler errors with some coarray examples
and one example using procedure pointers and abstract interfaces.

I've raised tickets with Intel about these examples.

As Steve says the 'community edition' is free.

As a developer having a single package with two Fortran compilers, an
MPI library and the Intel C++ compiler is very attractive to me.

If you already have a licence for ifort the upgrade
is free, and you can get support immediately.
It took me about 15 minutes to do this upgrade.

Congratulations to Intel for this,
and thanks to Steve for bringing it to people's attention.
