Displays
========

   When GDB is told to display something using the `display' command,
the results of the display are annotated:

     ^Z^Zdisplay-begin
     NUMBER
     ^Z^Zdisplay-number-end
     NUMBER-SEPARATOR
     ^Z^Zdisplay-format
     FORMAT
     ^Z^Zdisplay-expression
     EXPRESSION
     ^Z^Zdisplay-expression-end
     EXPRESSION-SEPARATOR
     ^Z^Zdisplay-value
     VALUE
     ^Z^Zdisplay-end

where NUMBER is the number of the display, NUMBER-SEPARATOR is intended
to separate the number from what follows for the user, FORMAT includes
information such as the size, format, or other information about how
the value is being displayed, EXPRESSION is the expression being
displayed, EXPRESSION-SEPARATOR is intended to separate the expression
from the text that follows for the user, and VALUE is the actual value
being displayed.
