Use the following techniques to select variable names from windows for
  the operations described in the Additional Topics.

  When selecting names, follow the syntax of the source programming
  language:

   -  To specify a scalar (nonaggregate) variable, such as an integer,
      real, Boolean, or enumeration type, select the variable's name.

   -  To specify an entire aggregate, such as array or structure
      (record), select the variable's name.

   -  To specify a single element of an aggregate variable, select the
      entity using the language syntax.  For example:

       +  The string arr2[7] specifies element 7 of array arr2 in the C
          language.

       +  The string employee.address specifies the component address of
          record (structure) employee in the Pascal language.

   -  To specify the object designated by a pointer variable, select the
      entity following the language syntax.  For example, the string
      *int_point specifies the object designated by pointer int_point in
      the C language.

  Select character strings from windows as follows:

   -  In any window, to select a string delimited by blank spaces, use
      the standard DECwindows Motif word-selection technique:  position
      the mouse pointer on that string and then double click MB1.

   -  In any window, to select an arbitrary character string, use the
      standard DECwindows Motif text-selection technique:  position the
      mouse pointer on the first character, press and hold MB1 while
      dragging the mouse pointer over the string, and then release MB1.

   -  In the debugger source view, you also have the option of using
      language-sensitive text selection.  To select a string delimited by
      language-dependent identifier boundaries, position the mouse
      pointer on that string and press Ctrl/MB1.

      For example, suppose the source view contains the character string
      arr2[m], then:

       +  To select arr2, position the mouse pointer on arr2 and press
          Ctrl/MB1.

       +  To select m, position the mouse pointer on m and press
          Ctrl/MB1.

      You can change the key sequence for language-sensitive text
      selection as explained in the Defining the Key Sequence for
      Language-Sensitive Text Selection topic.
