 Syntax

     GETREADER(<oGet>, <GetList>, <oMenu>, <nMsgRow>,

 Arguments

     <oGet> is a reference to a Get object.

     list.

     <oMenu> is a reference to a TopBarMenu object.

 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.
