Record parts

A record part defines a structure (a hierarchical layout of fixed-size data elements in storage) and an optional binding, which is a relationship, of the record to an external data source (file, database, or message queue). The binding is specified by the record type and associated properties. The record is used as a type when declaring variables (including parameters), and the structure defines the layout of the storage allocated for the variables. The data source binding determines the type of I/O operations generated for the variable when the variable is used in an I/O statement.

You may use a record variable in an EGL function in the following contexts:

• In most cases, in a statement that copies data to or from data storage

• In an assignment statement

• As an argument that passes data to another program or function

You also may use a record variable in these ways:

• As a parameter that receives data into a program

• As a parameter that receives data into a function
