How to know if alpha is empty

[javiersan]

Hello,

I want to know if an alpha object is empty. I can do the following:

Code: Select all

series ll=@len(myalpha) !maxl=@max(ll)

where myalpha is the alpha series and !maxl will be zero if the alpha is empty.

Is there a command to replicate this?

Thanks,

Javier

That's as good as you're going to get, I think.
