# Enterprise Service Tools Single-Service Wizard for CICS Web Services will generate WSBind and PL/I include files for the Top-down scenario

This topic describes the ability to generate artifacts for PL/I files with the top-down scenario.

Problem:

Users of Rational® Developer for System z® utilize the EST perspective to create Service-oriented applications from the Enterprise artifacts. Single service projects in EST allow the users to expose single business functions (or applications) as service interfaces.

While all of the available scenarios have so far been supported for applications written in COBOL, for PL/I, only the bottom-up for CICS® Web Services have been supported.

Solution:

This feature adds a PLI-ENTERPRISE option as available language when running the generation of the web services artifacts (these artifacts are, the WSBind file and any PL/I INCLUDE files that encapsulate service interface parameters).

Using the Enterprise Service Tools Web Service Wizard:

The Web Services for CICS - Create New service implementation wizard, Application properties tab, Application language entry field has PLI-ENTERPRISE as an available option, in addition to the already existing COBOL default option.
