Question: Typesetting: What does this example demonstrate

I do not understand the following typesetting example from this helpage.

with(Typesetting)

interface(typesetting = extended)

Typeset(BesselJ(v, x))

BesselJ(v, x)

(1)

NULL

Same output without Typeset

BesselJ(v, x)

BesselJ(v, x)

(2)

NULL

Download Typeset.mw

Why the Typeset call when the output does not change. Is the helppage maybe broken? It says Examples but lists only one.

If MapleSoft read this: Some more typesetting examples would be helpfull.

Please Wait...
