Where there are endless examples of said point, this one seemed pretty representative

> dPdz2 := x-> piecewise(x<1,1,x>1,1/x);

dPdz2 := x -> piecewise(x < 1, 1, 1 < x, 1/x)

>dPdz2(z);
{ 1 z < 1
{
{ 1/z 1 < z


> dPdz2(0);
Error, (in dPdz2) division by zero

MAPLE IS THE VIRUS!

take the limit

works for me...? (try the restart command, you might have defined your function differently before)

> f:=x->piecewise(x<1,1,x>1,1/x);

f := x -> piecewise(x < 1, 1, 1 < x, 1/x)

> f(z);

{ 1 z < 1
{
{ 1/z 1 < z

> f(0);

1

^^ what version you got? it could just be Maple 7.

I am using 10. That could be it.

Are you loading any packages that would change the behavior of piecewise? like
with(Student); or something?

have you tried to define it like
>f(x):=piecewise(...);
>subs(x=0,f(x));
