How do you enter h in a Euler's method problem? I need to change h=0.1 to h=0.05

I'm using the 2D input in Maple 14.

So far I have this:

> DE2 := diff(y(t), t) = 3+t-y(t);

> Euler(DE2, y(0) = 1, t = .4);

> Euler(DE2, y(0) = 1, t = .4, output = Error);

> Euler(DE2, y(0) = 1, t = .4, output = information);
