7 Examining Data
****************

DDD provides several means to examine data.

   * The quickest way to examine variables is to move the pointer on an
     occurrence in the source text.  The value is displayed in the
     source line; after a second, a popup window (called "value tip")
     shows the variable value.  This is useful for quick examination of
     several simple values.

   * If you want to refer to variable values at a later time, you can
     "print" the value in the debugger console.  This allows for
     displaying and examining larger data structures.

   * If you want to examine complex data structures, you can "display"
     them graphically in the data window.  Displays remain effective
     until you delete them; they are updated each time the program
     stops.  This is useful for large dynamic structures.

   * If you want to examine arrays of numeric values, you can "plot"
     them graphically in a separate plot window.  The plot is updated
     each time the program stops.  This is useful for large numeric
     arrays.

   * Using GDB or DBX, you can also "examine memory contents" in any of
     several formats, independently of your program's data types.  

Value Tips

Just move the pointer on a variable.

Printing Values

Printing a value in the debugger console.

Displaying Values

Displaying structures as graphs.

Plotting Values

Displaying values as plots.

Examining Memory
