Pauline,
I think the simplest alternative (although bulkier), is to have a string
variable with the same dimensions as your grid that contains the flag
meanings for each cell. It seems awkward to load huge flag_value and
flag_meaning attributes, but it saves lots of space, and it lends itself
to automated use. The string variable does none of those things.
Grace and peace,
Jim Biard
