When running the Class Browser using the DO command, you can use the following additional parameters and syntax:

В Copy Code

The following table describes the optional parameters you can use when running the Class Browser using the DO command.

Parameter Description

If no default class is specified, the class library is selected. If a class member is specified, the class member appears selected in the member list of the Class Browser.

Specifies the initial type filter for the classes displayed in the Class Browser. To change the filter in the Class Browser, choose another value in the type list of the Class Browser.
