Hi Ryo, Well this is because long ago there were some tools that let us write a file type "hdf movie". http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/animations-gif-images/OVERVIEW The default for the FRAME command when issued with no argument was the HDF format. However the library that gave us this capability hasn't been available in quite a while, and so for recent versions of Ferret we've just written this message on a FRAME with no argument. You're probably right to suggest that that it would be better to do something different; perhaps issue a note on the first instance and do nothing. I don't have a suggestion about flickering when animating on the fly -- anyone else have an idea??

A FRAME command without qualifiers isn't terribly important to me. I was just using it as a means of reducing the flickering of on-the-fly animation: yes? repeat/l=1:120 (fill/l=1/k=1 temp) !! flickers. yes? repeat/l=1:120 (fill/l=1/k=1 temp; frame) !! Easier to see. (Is there an alternative?) Regards, Ryo |
