To help developers who are implementing applications that use portlets, a new environment variable was created: II_W4GL_PORTLETBLOCKING_DEFAULT. Any application started with this environment variable set will use the environment variable setting as the portlet blocking default for all CALLFRAME statements issued from within a portlet script.

Because this environment variable is only checked at application startup, changing its value within an application will have no effect. Valid values are listed in Environment Variables.

For complete information about the II_W4GL_PORTLETBLOCKING_DEFAULT environment variable, see the Workbench User Guide.
