Naming

It is possible to reference structures within MDO data by name from NCL. A map must be attached to the MDO so NCL can use this map to associate names with physical structures which can occur within the data. By definition, components are hierarchically arranged. This means that to reference one component enclosed within another, a concatenation of the enclosing structure names is required to identify the enclosed one.

For example, the name:

MDO=FILE1REC.DOMAIN.SUBDOMAIN.LU

might be used to reference the structure LU, within a structure called SUBDOMAIN, which is contained in a structure called DOMAIN, which is within the data in an MDO called FILE1REC.

To reference all data contained within an MDO, only specify the single MDO name segment, as follows:

MDO=FILE1REC
