Default Map

A default mapping, using the $NCL map can be used to maintain NCL variable data in a file. Individual data records up to 32K and containing transparent variable data, are supported in this manner. Each variable exists in a vector format and can be isolated using length fields and data tags.

When using the $NCL map, the file statements reference one or more NCL variables in the normal manner. The actual structure of the record can be understood by referring to the distributed $NCL map.
