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.
