Getting Started


New function for VisualAge Generator 4.0

VisualAge Generator V4.0 introduces both functional enhancements and new development and runtime platforms.

VisualAge for Java interoperability

VisualAge Generator is fully integrated into the VisualAge for Java Enterprise development environment. In the Developer on Java platform:

WebSphere Rapid Application Development Support

This new programming model provides traditionally skilled programmers a fast path to creating scaleable e-business systems using VisualAge Generator, WebSphere Studio, and WebSphere Application Server. This new function enables programmers to develop main transaction programs, using 4GL programming techniques, that can interact with end users through a web browser.

Functions

In VisualAge Generator V4.0, functions replace statement groups and processes to handle the logic for a program. During migration to V4.0, the Statement Group parts and Process parts are converted to Function parts.

A Function part is used the same way as a Process or Statement Group part with the following support:

Object Scripting

In VisualAge Generator V4.0, you can access non-VisualAge Generator objects from within the 4GL through the synchronous execution of a Smalltalk or Java method (Object Script). A new EZE word, EZESCRPT, allows the you to make a call to a Smalltalk or Java method or an Enterprise JavaBean from the 4GL logic.

A new set of wizards and help guide you through the task of building basic method logic (object scripts) in the target language (Java or Smalltalk).

VisualAge Generator Templates Enhancements

VisualAge Generator Templates now provides:

Solaris Runtime Support

VisualAge Generator programs can be generated as C++ programs that support:

Enterprise JavaBeans (EJBs) support

VisualAge Generator support for Enterprise Java Beans (EJBs) will allow Java clients to call VisualAge Generator server programs through an intermediary session bean.

Support for calling server programs through an EJB session bean is only provided in VisualAge Generator Developer on Java development platform.

Automated IC Packaging support

VisualAge Generator support for IC packaging feature allows you to package your GUI system in a modular way. Each ENVY application containing GUIs can be packaged into a separate file (typically 100K-1Mb in size) called an IC (Image Component) file which can be repackaged and distributed separately. Also, the runtime system loads these ICs dynamically as needed.

Native Oracle support

Generated programs can now access Oracle databases directly on CICS for AIX and CICS for Windows NT platforms.

Enhanced Container Details part

The Container Details part has been enhanced for Smalltalk GUI clients to support proportional column widths, tabbing between cells, multiline headings, and common controls at the cell level.

Accessing remote VSAM files

Now when you test programs with the Interactive Test Facility, you can access VSAM files that reside on a remote OS/390 system.
