WREAD([<window name>])

-----------------------------------
Returns true if specified window is involved in current READ.
Return value - Logical
-----------------------------------

WREAD() returns a logical true value if the specified window is
participating in the current READ.  If the specified window is not
involved in the current read, false is returned.

A window can participate in a READ by:

        . Including the window's title in the READ WITH clause.  Windows that
typically are not involved in a READ can participate in the READ by
including the WITH clause.  Browse windows, memo and text editing
windows, FoxPro system windows and so on can participate in a READ by
including them in a READ WITH clause.

        . Issuing @ ... GET in the window.  A READ can encompass multiple
windows by issuing @ ... GETs in more than one window and then issuing
READ.

Clauses
-------

<window name>
        To determine if a window is participating in a READ, include the
<window name> in WREAD().

        If a window name is not included, WREAD() returns a logical value for
the window that is currently frontmost (that is, the window whose name
would be returned by WONTOP()).
