Tony,

You should add the NUM= keyword sequence.  If you don't only one
match will be returned.

>And here you can see none of those three levels are missing:

>GRDLIST LG.299 NUM=ALL PAR=Z LEV=150 200 250

Your second GRDLIST example shows that there are three grids and that
the first one is the one at 150 mb.  If you add NUM=3 to your first
GRDLIST invocation, you will get values back for each of the grids listed
in the second example.

Yep, that did it. Thanks!
