I corrected it in both listings. 2) HP71B BASIC, as mots BASICs, is not case sensitive. 3) It would be nice if someone can numerically approximate the d2y/dx2 for dy/dx = f(x,y). Any idea? When say dy/dx=y, approximating the second derivative with x and an increment of x leads no where! I am open to suggestions. Namir
