[Description]
Pointer to the active <A HREF="$$LINK(GR_WIN_VARS)">GR_WIN_VARS</A> struct.

[Explanation]
<I>gr_active</I> is a pointer to a <A HREF="$$LINK(GR_WIN_VARS)">GR_WIN_VARS</A> struct that contain most of the data used by
the Graph application and other graph-related apps. <I>gr_active</I> points to the
<A HREF="$$LINK(GR_WIN_VARS)">GR_WIN_VARS</A> struct containing all the information for the active graph
(whereas <A HREF="$$LINK(gr_other)">gr_other</A> points to the information for the second graph in two-graph mode).
As the calculator user switches between the two windows in two-graph
mode, the pointers in <I>gr_active</I> and <A HREF="$$LINK(gr_other)">gr_other</A> are swapped so that
<I>gr_active</I> is always referring to the active graph. The members of a
<A HREF="$$LINK(GR_WIN_VARS)">GR_WIN_VARS</A> struct are given along with an explanation of the
contents of each in the description of <A HREF="$$LINK(GR_WIN_VARS)">GR_WIN_VARS</A>. None of the data should be changed directly by a program,
but can be accessed for use. System routines may be called to
change many items (for example, <A HREF="$$LINK(vat.h/VarStore)">VarStore</A> may be used to change the
graph system variables), but some data is for internal use only and should
only be changed by the appropriate system app.
