Format 2 This format allows you to obtain information about mapped data objects (MDOs) and
maps.

OPT
specifies that you want to obtain information about MDO variables and maps.
MAPNAME
specifies that you want NCL to return the name of the map being used by the
supplied MDO operand. If the MDO is unmapped, a null value is returned.
MAPELEMENTS
specifies that you want the names of defined elements returned. Only the
names of those elements defined in the data dictionary as local elements
within the structure of the supplied MDO operand are returned. If the MDO
operand defines an element that has subordinate elements, or if it defines a
group or field name, no data is returned.
MAPFIELDS
specifies that you want the names of defined groups or fields returned. Only
the names of those groups or fields defined to the data dictionary within the
structure specified are returned. If the MDO operand defines just a field
name, or an element that has no groups or fields, no data is returned. If the
MDO operand specifies a group name, only those fields defined within that
group are returned.
MDOELEMENTS
specifies that only the names of those elements present within the actual MDO
structure specified are returned. These elements may be local or inherited.
This operand is different from the operand MAPELEMENTS, which provides
only the names of local elements. An inherited element is one that follows
certain nonstandard naming conventions as permitted by the creator of the
map.
