Screen Hierarchy

Three Screen Levels

The debugger supports three levels of screens:

Usage Screen

The Usage screen is an informational global help screen that contains a list of the debugger commands and a brief description of their functions. The Usage screen is the default screen for the MENU command.

Activity Screens

Activity screens are screens that provide you with an area for specifying command options. The debugger provides activity screens for the AT, DEBUG, LIST, RESUME, SET, and SNAP commands. You can initiate these commands from the activity screens once you've entered the necessary information in the specification area.

Help Screens

Help screens provide two types of assistance:

• Command-specific help screens supply tutorial information on all the debugger commands. When the command is one that uses an activity screen, the help screen for that command also describes the field options.
• Global help screens provide information not associated with a particular command. For example, the Symbols screen enables you to choose a display of program and debugger symbols for the current session, and the Keys screen displays site-specific PF-key assignments.
