There is a constant global variable defined in another module.

I would like to manipulate this variable during run time (as I can't change in the other module and remove the const keyword).

I know that constants are put in ROM ...

The code will be downloaded to a micro controller (leopard powerpc 5643) , so I think that constants will be in the Flash Memory (not the normal PC ROM)

I have tried something like this and the compiler produced an error during compilation:

```
const int global_Variable = 0;
const int* ptr = &global_Variable;
*ptr = 5;

```

So , do you know any other way to accomplish this ?
