A record type is a data type whose values contain a specified collection of named fields, each with its own type. A record describing a point might have numeric fields
x and y and a text field label. Selecting point.x identifies a component by its field name. Oberon defines records in this way and permits record extension by additional fields.[ref]The logical grouping is distinct from its byte layout. An implementation may insert padding to satisfy memory alignment; for example, a small integer field followed by a larger one need not occupy exactly the sum of their payload sizes. In C programming language, the corresponding aggregate is a structure, with field ordering and padding governed by the language's representation rules.[ref]
