I must really say that higher analysis with Mathematica 4.0 is full of
traps! Just to inform you:

During a (not too difficult) calculation I had to calculate

Limit[SinIntegral[p*a],a->Infinity]

After 

<<Calculus`Limit`

I got as a result Pi/2. This is of course only correct iff p>0. For p<0
the correct limit is -Pi/2.
