Developing EGL programs for the VSE environment

Rational® Business Developer provides a Generation for VSE feature that you can use to generate EGL as COBOL source for the z/VSE® environment.

To use the Generation for VSE feature, you must do the following things:

Install the feature and then enable the feature by purchasing and applying the license for IBM® Rational Business Developer Extension for VSE. The feature provides the COBOL generation capability for the VSE environment.
Install and customize IBM Rational COBOL Runtime for z/VSE, which provides the runtime support for the VSE environment (similar to the runtime support for z/OS® that is provided by IBM Rational COBOL Runtime for zSeries®).

The following highlights apply to developing for the VSE environment:

You can develop traditional 3270 or batch applications. You can also develop VGWebTransaction programs.
Developing for VSE CICS® is similar to developing for z/OS CICS; developing for VSE Batch is similar to developing for z/OS batch. Therefore, much (but not all) of the information in the online help that describes these two z/OS environments also applies to the VSE environment.
You have two options for generation in the VSE environment:
- You can use the EGL VSE build server to prepare the output of COBOL generation for the runtime environment, as in the z/OS environment.
- You can use a preparation process that is similar to that used by VisualAge® Generator. This process involves the following templates and procedures:
  - Preparation JCL templates that are included with the Generation for VSE feature
  - Preparation JCL procedures that are included with IBM Rational COBOL Runtime for z/VSE
Set the USEVSEBUILDSERVER symbolic parameter to YES to use the VSE build server. For more information, see Predefined symbolic parameters that can be set by the user.

For more information about developing and generating EGL programs in the VSE environment, including compatibility considerations for VSE that differ from z/OS, see Generation for VSE Feature Reference.

For more information about installing and customizing the VSE runtime support, refer to the Program Directory for Rational COBOL Runtime for z/VSE (GI10-8803-00).
