Robert,

For glevel 30:0, gfunc=obs, in garp, you need to click
on the "layer" radio button.

When clicking on the "wind" vector function, it sets the plot
type to level by default which grays out the level 2 button.
Clicking on the layer button should activate level 2 which
is needed to use glevel=30:0.

In any command line program it would be glevel = 30:0, instead of
the semi-colon which you show above.
