Doctor Fortran in "Source Form Just Wants to be Free"
Autor: Steve Lionel (Intel) Publicado em 11/01/13 0
In the beginning, there was only one source form for FORTRAN (as it was then known) programs. Each statement was exactly 72 characters long - no more, no less. (See note below.) Columns 1-5 were for statement labels, whole line comments were indicated with a C in column 1, and column 6 was reserv...
Doctor Fortran in "I Can C Clearly Now, Part I"
Autor: Steve Lionel (Intel) Publicado em 11/05/12 1
Spend any time in the comp.lang.fortran newsgroup, or other places where programming languages are discussed, and you’ll soon see a new “Which is better, Fortran or C?” thread show up. These never fail to produce heated comments from people who should know better. My answer is that neither is “be...
Doctor Fortran Gets Explicit - Again!
Autor: Steve Lionel (Intel) Publicado em 05/01/12 11
Nearly 11 years ago (!) I wrote an item for the Visual Fortran Newsletter on explicit interfaces in Fortran. In recent weeks, I have had to refer quite a few customers to this article, suggesting that many Fortran programmers don't understand the role and rules of explicit interfaces. However, wh...
Doctor Fortran in "Lest Old Acquaintance Be Forgot"
Autor: Steve Lionel (Intel) Publicado em 23/12/11 3
In some of my earlier posts I've discussed new features in the Fortran language that might be unfamiliar to some.  But this time I'm going to go the other way and describe some really old language features - so old that many newer Fortran programmers are mystified when they see them - but these f...
The Real Doctors of Fortran
Autor: Steve Lionel (Intel) Publicado em 22/09/11 7
In this blog, I refer to myself as "Doctor Fortran".  It's a joke that started more than ten years ago when I decided to write an "advice column" for what was then the Digital Visual Fortran Newsletter.  Everyone liked it so much I stuck with it, but I've always been aware of the people who deser...
Introducing Intel® Fortran Studio XE 2011
Autor: Steve Lionel (Intel) Publicado em 06/09/11 5
Let us return to those thrilling days of yesteryear. Yes, I mean November 2010 when Intel® Parallel Studio XE was first released. This suite of high-performance computing development tools included new versions of the Intel C++ and Fortran compiler products, (now renamed "Composer XE"), and two n...
Thirty Years of Zonker Kookies
Autor: Steve Lionel (Intel) Publicado em 20/10/10 9
It is a beautiful autumn day here in Southern New Hampshire. The air is clear and crisp, the sun is bright and the trees have (finally!) brought out some color, which I can see looking out the window near my cube.  But soon, I will pack up the rest of my things and leave that view, and the cube, ...
Doctor Fortran in "Think, Thank, Thunk"
Autor: Steve Lionel (Intel) Publicado em 02/09/09 2
One of the various responsibilities I have is for the compiler samples (both Fortran and C++).  For Intel Visual Fortran, we have a lot of samples - for the other compilers, fewer.  The Windows Fortran samples are a mixed lot; some came to us from Microsoft Fortran Powerstation (with or without e...
Doctor Fortran in "I've Come Here For An Argument, Side 2"
Autor: Steve Lionel (Intel) Publicado em 10/07/09 11
My earlier post, "I've Come Here For An Argument", was very popular with my fellow support engineers, as it provided a convenient answer to questions they frequently receive.  (For me too, which in part is why I wrote it!) But some people (cough, Ron, cough) are never satisfied, and I've been ask...
Doctor Fortran in "Revert! Revert! The End (of the format) is Nigh!"
Autor: Steve Lionel (Intel) Publicado em 01/07/09 4
Recently, a customer wrote in our User Forums that he wanted to write out the values of an array, all in one line, where the number of elements was not known at compile time.  His first attempt at this was:write (30,'(2x,f8.2)') array and he was dismayed to find each element written on a new line...
