Enterprise Generation Language (EGL) is a programming language that you can use to focus on business problems instead of software technologies. Within the Rational® development environment, you can use EGL wizards and other tools to write complex applications with minimal effort.
EGL Programmer's Guide
The EGL Programmer's Guide covers using EGL within the Eclipse Integrated Development Environment (IDE), as well as some of the common programming tasks that EGL developers perform.

    - Introduction
      These topics explain the fundamentals of using EGL in the Eclipse IDE, as well as changes to the EGL language and IDE in this version.
    - Contents of an EGL application
      EGL applications contain projects, packages, folders, and files.
    - Properties
      Properties set specific options for parts. In general, you specify the properties when you create the part and then the properties are static. In certain circumstances, however, it is possible to change a property dynamically.

        You can use TCP/IP to access a VSAM file on a remote z/OS® or z/VSE® system from EGL-generated Java™ code or from the EGL debugger. Use CICS® to control the operation if you typically access the file through CICS transactions.
      - Installing and configuring remote VSAM support for VSAM Connector Server
        You can use TCP/IP to access a VSAM file on a remote z/OS® system from EGL-generated Java™ code or from the EGL debugger. Use the VSAM Connector Server to control the operation if you typically access the file through a batch job.
      - Setting preferences for the EGL debugger
        The EGL debugger has two main pages of preferences: the first contains general preferences, and the second contains a list of programs or services to debug in generated code (Java™ or COBOL). An additional page is available if you have set the EGL DLI Developer capability.

- Responsive Design Support in IBD
  What is Responsive Design? Responsive design is an approach for creation of web pages that automatically scales its content and elements to match the screen size on which it is viewed. So, instead of designing multiple websites for different devices with variable screen sizes, we can design just one website that scales up or down automatically, to match the device it’s being viewed on.

Remote VSAM support for z/OS® using TCP/IP

You can use TCP/IP to access remote VSAM files when you run the EGL debugger or when EGL-generated Java™ code is running on any supported platform.

To use TCP/IP to access remote VSAM files, do as follows:

Satisfy the access requirements specified later.
Set up a resource association part and reference that part from the build descriptor that you use for debugging or generating your code.

You can access the file as a local VSAM file in either of the following circumstances:

You normally access the file through CICS® transactions, under the control of CICS®. For setup information, see Installing and configuring remote VSAM support for CICS.
You normally access the file through a batch job. For setup information, see Installing and configuring remote VSAM support for VSAM Connector Server.
