finding maximum to certain date

[dasilver]

I want to create a series that is the maximum value of another series up to that date. Is there a way to do this in EViews? I can create a 1-column matrix that is equivalent to what I want, but I cannot convert it back into a time series.

Thank you.

Aren't you just talking about the @cummax function?

that is exactly what I needed - thanks!
