Dear Graham

First, think you very much for your kindly help.

I opened the attached files. In your model,

the max value curve is recorded.

Actually, I only want to know the max value, not the max value curve.

Can MapleSIm tell me this? or can not?

I am a green hand of MapleSim,

 and I am look forward your further help.

Think you.
