Our company is currently involved in a modernization project of our
seismic processing system. Most of our code is written in fortran77.
We are currently in a debate as to whether to go with fortran90 or C++.
One of the reasons for considering C++ is the perceived difficulty in
finding programmers who know fortran. Another reason is the maturity of
fortran90 compilers. We have found fortran90 to run our code less
efficiently than fortran77. In either case, we do not intend to rewrite
all of our current fortran77 code in a new language, but would write the
backbone of our processing system in the new language as well as any new
code. Our code is currently Cray dependent, and part of this effort
will be to make the code portable.
I would appreciate any comments on the above two fears concerning
fortran90.
