Using Records. In my limited time using Erlang I've seen records used primarily for two things. First, records are used to keep state, especially when using the generic server behaviour. Since Erlang is side-effect free state cannot be kept globally. Instead it must be passed around from function to function.

Erlang is a dynamically typed language. Still, it comes with a notation for declaring sets of Erlang terms to form a particular type. This effectively forms specific subtypes of the set of all Erlang terms. Subsequently, these types can be used to specify types of record fields and also the argument and return types of functions. 1 Records 1.1 Records and Tuples. The main advantage of using records rather than tuples is that fields in a record are accessed by name, whereas fields in a tuple are accessed by position. To illustrate these differences, suppose that you want to represent a person with the tuple {Name, Address, Phone}.

Therefore, record expressions are not understood by the shell unless special actions are taken. For details, see the shell (3) manual page in STDLIB. Erlang has the extra facility to create records. These records consist of fields.

2 Public key records. This chapter briefly describes Erlang records derived from ASN1 specifications used to handle public and private keys. The intent is to describe the data types and not to specify the semantics of each component. For information on the semantics, please see the relevant standards and RFCs.
