Section 8,6,2: Field_References

 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.
