Locate good data point

[Jens-Olaf Beismann <jobeismann@xxxxxxxxxxxxxxx>]

Dear Ferreters,

using output from an Atlantic ocean model, I'm trying to locate the 
i-index of the westernmost ocean point at a given latitude. Example: At, 
say, 30 degN, the westernmost ocean point would be roughly at 80 degW at 
the surface, and a bit more to the east at greater depths.
I could of course LIST/y=30n/k=1/form=(e) TEMP to see at which index the 
values switch from special_value to real data at this level, but since I 
want to do it for all depths and all latitudes, I'm looking for something 
more automatic.

Any good ideas?

Cheers,

Jens-Olaf
