Does anyone know how to do register based calling under DJGPP?

Thanx,

This means, "Define a two-dimensional array of pointers to defPt."

This means, "Allocate space for a single object of type defPt."

If you want to allocate alll the space for them, you need to iterate
through the two-dimensional array:

    for (int i = 0; i < 25; i++)
    for (int j = 0; j < 25; j++)
        View[i][j] = calloc(1, sizeof(defPt));
