'''Program'''

An EGL Program part is a generatable logic part with one entry point. Each Program part contains a main() function, which represents the logic that runs at program start up. A program can include other functions and can access functions that are outside of the program. The function main() can invoke those other functions. Programs functions are composed of a set of EGL statements, variables, and constants.

<source lang="java">

Program HelloWorld

const GREETING string = "Hello, ";

function main()

myName string = "John";

sayHello(myName);

end

function sayHello(name String in)

SysLib.writeStdOut(GREETING + name + "!");

end

end

</source>

'''Record'''

EGL has a specialized type of record called '''''SQLRecord''''' that is used to exchange data with a relational database. In this example, the record '''''Employee''''' is bound to a table (or view) named '''''Employee'''''.

Line 40 ⟶ 61:

* In this example, the record '''''Employee''''' is bound to a table (or view) named '''''Employee'''''.

'''Service'''

An EGL Service part contains public functions meant to be accessed from other applications or systems. In this example, a service with two functions is defined. The first function, ''getEmployees'', returns an array of records populated from the records in a database. The second function, ''addEmployee'' adds a new record to the database and returns a true or false depending on whether the record was added successfully.

<source lang="java">

Line 67 ⟶ 90:

end

</source>

* In EGL, code is organized in packages (like [[Java (programming language)]])

* The first function, ''getEmployees'', returns an array of records populated from the records in a database.

* The second function, ''addEmployee'' adds a new record to the database and returns a true or false depending on whether the record was added successfully.
