The Variable Menu gives on-screen access to the funtions of the Locals Window.
To use any of these functions, first use the left mouse button to select a
variable from the display. Then select:
<DL>
<DT><A NAME="menus_edit">Edit</A>
<DD>Edit the value of the variable
<DT><A NAME="menus_fmt">Format</A>
<DD>Change the display format of the variable
</DL>
<H3><A NAME="display">Locals Display</A></H4>
The Locals Window Display consists of a scrolled listbox which contains all
local variables, one per line. To use any of the functions of the Locals Window,
use the left mouse button to select any element from the Display.
<P>Pointers, structures, and classes appear in the display with small exapansion
box before their names. To <A NAME="display_deref">dereference pointers</A> or
<A NAME="display_struct">view the members of classes or structures</A>, click
the closed expansion box (which appears as a small plus sign, "+") to "expand"
the listing. The expansion box changes to a minus sign, "-", indicating that the
display is now open. Pointers, structures and classes may be expanded recursively
to allow multiple pointer dereferences and embedded structure viewing.
<P>The Locals Display updates after every execution of the program and highlights
in blue those variables whose values have changed.</P>
<P>The Locals Window will, by default, display all pointers in hexadecimal and all
other variables in decimal. To change the display format for a variable, select
the Format option from either the Variable Menu or the <A HREF="#display_popup">
Locals Pop-up Menu</A>.
