How do I get VARPG Program to repaint?

I have a tight loop, where I'm reading from a PC ODBC file and loading into
an AS/400 DB2 file.  For each record I update an editbox on the window like
this:

     C                   Eval      %setatr('Win01': 'ENTSEASON': 'Text') =
     C                                 'On Record: ' + %Char(RecordNumber) +
     C                                 ' Bad: ' + %Char(BadNumber)

The edit box gets updated, but, the rest of the window never gets repainted.
That is, if I bring another window to the front, and then click on the task
bar this VARPG program window never gets shown.  If I minimize all windows
on top of it, the window is shown but all grayed out (none of the controls
are re-painted) and the edit box shows the changing values.

How do I get this program to behave more like a "normal" windows program?

I remember in Delphi I would do an Application.ProcessMessages()
In C I would do an invalidate_rect(hwnd, xleft, ytop, xright, ybottom,
false); where x and y were window rectangles.
