Selection Area

List of Procedures

The selection area presents a list of the debugger commands and global help screens that you can initiate from the screen. You can select the next action by entering any character other than a blank or an underscore in the response field to the left of an activity or help function.

Two Sections

You can select actions from one of two sections:

• Section A displays the choice of command-specific activity and help screens:

  NEXT  _ ACTIVITY OR  _ HELP
        _ AT     _LIST    _SET    _SNAP  _RESUME  _ DEBUG  _WHERE
  
        _EXIT    _PROMPT  _QUIT   _IOUSER
  

• Section B displays the choice of global help screens:

  HELP SCREENS:   _ USAGE    _ SYMBOLS    _ KEYS
  

Command-specific Activities

When choosing from Section A, you first select Activity (the default) or Help and then choose one of the commands. If you select Activity, the system can:

• Execute immediately an EXIT, PROMPT, QUIT, or IOUSER command
• Display the activity screen for an AT, LIST, SET, SNAP, RESUME, or DEBUG command
• Display the information requested by the WHERE command

Control keys can also be used to request activities.

Selecting Help If you select Help from Section A, the system displays a command-specific help screen.

If you mark the select byte for Activity or Help but do not choose a specific command, the system displays the activity or help screen for the current command. The debugger system displays an error message if there is no current command.

You can choose a global help screen from Section B.

Each of the activity screens and global help screens is described in detail later in this chapter.
