Fields within a record may be accessed collectively or
  individually.  Record references are either qualified or
  unqualified.

  A qualified reference refers to a typed data item and can be used
  wherever an ordinary variable is allowed.  Type conversion rules
  are the same as for variables.  Its form is:

     rname[.cfname...cfname].afname

  Unqualified references refer to a record structure or substructure
  and can be used (in most cases) like arrays, for example:

     rname[.cfname...cfname]

     rname    Is the name used in the RECORD statement to
              identify a record.

     cfname   Is a substructure field name within the record
              identified by record-name.

     afname   Is the name of a typed data item within a structure
              declaration.
