Hi Michael,

Can you explain more what you mean by DATTIM=last stops working after a minute 
or two?  How are you running sfmap continuously? How does DATTIM=last work for 
you, what is printed to the screen or device driver, and what happens exactly 
when it "stops"?

I was able to get this to work for SFFILE=metar and PROJ=mer (or any non-SAT 
projection), but explicitly defining DATTIM=1600 - it's 1619 UTC as I write 
this, and using DATTIM=last will attempt to plot 1700 UTC obs, which of course 
there are none in the metar file yet.    

So, I don't understand if the problem you are describing is the same as what I 
encountered just now.   Can you confirm that the DATTIM determined by your 
scripts returns data through SFLIST or SFMAP when entered explicitly?
