A Record-Constant provides a method of calculating a single numeric result value from a list of Record-FieldName values, and combining them together according to the definition of the Record-TypeName given by the Identifier-Operand. The result value is a Constant-ExpressionType suitable for use as an instruction operand, or for assigning to a record variable.
The Record-TypeName given by the Identifier-Operand determines how the Field-List will be evaluated. The Attribute-Expression entries are position-dependent, and are matched with the corresponding Record-FieldName entries from the Record-TypeName definition to determine their width and shift values. Attribute-Expression entries may be omitted, in which case the default values from the record definition are used in the calculation.
