Ken is absolutely right, but because you are a newbie,
I feel an obligation to get you started in the right
direction. I would write the code like this:

good = where( data NE -9999, count )
IF count GT 0 THEN data = data[ good ]

That will save you a couple of headaches down the road. :-)

Cheers,

David
