Legacy code - pearls that need to be looked after

It may surprise some - but old computer programs and "old" programming languages ​​are still the backbones of many applications in many areas of technology and science. At NASA, for example, a large part of the "mission critical code" is still there written in FORTRAN and in 2017 NASA launched an international competition to secure this legacy.

At GR-Consult, we draw on both of our programming expertise, on almost four decades of programming and software design and - thanks to our young employees - on the most modern development approaches and design concepts.

Even in the flood forecast, many components in the established systems play a central role. Often there are comparatively small programs in data processing, but sometimes there are also programs with tens of thousands of lines of code.

With the revision of all interface programs created since 2002 for the connection of the numerical models in FEWS, GR-Consult has secured these small, important components. They contain many detailed and special solutions and the particular value of the update is that we can modernize the entire system without changing long-established processes and interfaces.
