How do you read in and then call up data in binary format. It is in the
type that is used in GrADS where it is organized as:

Time 1, Level ?, Variable slp
* variable slp only has one level
Time 1, Level 1000, Variable z
Time 1, Level 850, Variable z
* then levels 700, 500, 400, 300, 250, 200, then
Time 1, Level 150, Variable z
Time 1, Level 100, Variable z
Time 1, Level 1000, Variable t
Time 1, Level 850, Variable t
* then levels 700, 500, 400, 300, 250, 200, then
Time 1, Level 150, Variable t
Time 1, Level 100, Variable t
Time 1, Level 1000, Variable td
Time 1, Level 850, Variable td
Time 1, Level 700, Variable td
Time 1, Level 500, Variable td
Time 1, Level 400, Variable td
Time 1, Level 300, Variable td
Time 1, Level 1000, Variable u
Time 1, Level 850, Variable u
* then levels 700, 500, 400, 300, 250, 200, then
Time 1, Level 150, Variable u
Time 1, Level 100, Variable u
Time 1, Level 1000, Variable v
Time 1, Level 850, Variable v
* then levels 700, 500, 400, 300, 250, 200, then
Time 1, Level 150, Variable v
Time 1, Level 100, Variable v
Time 2, Level ?, Variable slp
Time 2, Level 1000, Variable z
Time 2, Level 850, Variable z
Time 2, Level 700, Variable z
Time 2, Level 500, Variable z
Time 2, Level 400, Variable z
.
.
.
etc

I'd like to create an array organized with time constant and the level
changing for each variable for each time. Each of these is done for a
gridded latitude and longitude set around the globe.
Thanks for any help.
