Intuitive Access to ECBs

TPF/GI’s ECB window is a compact, graphical, intuitive display of ECB contents that users can browse and edit. The ECB window gives access to everything a programmer needs to know or change about an ECB:

• the Program Status Word,
  
• the ECB address, program name and program address,
  
• the register values,
  
• the data levels,
  
• the new dynamic data levels (DECBs),
  
• the current machine instruction,
  
• a tree view of the current program nesting level,
  
• the auto blocks,
  
• the EBW area,
  
• the EBX area,
  
• the data levels area,
  
• the system area,
  
• page 1 and page 2.

The ECB window is not only informative, but intuitive to use. For example, when programmers need to know what a register points to, all they have to do is double click the register and a window appears containing the contents at that register address. If programmers want to do a FLIPC, they can drag one data level and drop it on another. If they want to get core, they can drag a core icon and drop it on a data level.

These examples only scratch the surface of what the ECB window can do to help TPF programmers interactively test and understand their applications.
