NAM
The name (NAM) block provides additional fields for extended file
specification use, including parsing and obtaining the actual
file specification used for a file operation. On Alpha systems,
the long name block (NAML) can optionally take the place of a NAM
block (see NAML).

and a brief description of each field.
