```I'm using version 6.0.2.0, so the enourmous capabilities and
conveniences of the "Manipulate" function is available to me, and
hopefully you. But if not, here are two versions of viewing the
results:

(1)

Plot3D[x^2+y^2, {x,-100,100},{y,-100,100}]

(2)

Manipulate[Plot3D[a x^2+b y^2, {x,-100,100},{y,-100,100}], {{a,0,"a =
-100 to 100"},-100,100}, {{b,0,"b = -100 to 100"},-100,100}]
