After all the talk at the CDT summit about Fortran. I figured that
I should
probably play around with it and learn Fortran. Which path should I
follow?
Buy "Fortran 95/2003 Explained" by Metcalf, Reid, and Cohen and
peruse it.
As I understand it (I've forgotten the details) there was a
disagreement among
the g95 committers and gfortran split off leaving one (I think)
person still working on
g95. gfortran is officially blessed by GNU and will be included in
future releases
of gcc.
However, g95 is apparently better at compiling real code. We are
using (and
adding F2003 features) to gfortran.
You might want to look at:
1. Arrays (first class objects in Fortran).
2. Modules (compare with C++ namespaces).
3. Derived types (compare with C structs).
4. C interop (in F2003 for interoperability with C).
