f77, f90, f95....这都有啥改进呀。
老板好象又对f90感兴趣了

f90 allows pointer and recursive subroutines (I never used them)
you can also use module.
There may have been some improvement on matrix
operation.

No almost no software company still provides updated version of
Fortran compilers. The latest version of PGI Fortran compiler is actually
worse than the previous version.
I heard some modeling groups seriously consider rewritting all
codes in C, so they do not need facing this Fortran problem.

I've heard of that f90 is not as efficient as f77. probably coz of the
compiler....
