**The file, kascade7.inc, must be included with
kascade7.f for compilation. It contains common block
specifications and parameter definitions. The code must be
recompiled in order to change these parameters. A similar file, kascade3.inc, is required for kascade3. Example parameters
include:**

**Speed of light in vacuum [2.99792e8]**

Pi [3.141592654]
