 GETREADER()
 Execute standard READ behavior for a Get object
------------------------------------------------------------------------------
 Syntax

     GETREADER(<oGet>, <GetList>, <oMenu>, <nMsgRow>,
        <nMsgLeft>, <nMsgRight>, <cMsgColor>) --> NIL

 Arguments

     <oGet> is a reference to a Get object.

     <GetList> is an array of all the Get objects in the current Get
     list.

     <oMenu> is a reference to a TopBarMenu object.

     <nMsgRow> is a numeric value representing the row number on the
     screen where the message bar is located.

     <nMsgLeft> is a numeric value representing the left border of the
     row bar.

     <nMsgRight> is a numeric value representing the right border of the
     row bar.

     <cMsgColor> is a character string representing the color string to
     be used for the message bar.

 Returns

     GETREADER() always returns NIL.

 Description

     GETREADER() is a GET function that implements the standard READ behavior
     for GETs.  By default, READMODAL() uses the GETREADER() function to read
     Get objects.  GETREADER() in turn uses other functions in Getsys.prg to
     do the work of reading the Get object.

 Notes

     .  If a Get object's Get:reader instance variable contains a code
        block, READMODAL() will evaluate that block in lieu of the call to
        GETREADER().  For more information refer to the Get:reader reference.

 Examples

     .  This example sets the current Get object to the first GET in
        the Get list.  Then, a READ is performed on this GET which has no
        menu object, but includes a message bar at row 25 from column 0 to
        column 80.  The color of the text on the message bar is white with a
        red background.

        oGet := GetList [1]
        GETREADER (oGet, Getlist, NIL,25,;
                       0,80,"W+/R")

 Files   Library is CLIPPER.LIB, source file is Getsys.prg.
