A technique I have used in the past is to create a very small
pixmap window that I can erase and write a number in. Then I
just copy the pixmap window to the display window with a
Device, Copy command. In the FOR loop, the code looks like
this:

FOR j=0,n DO BEGIN
... ; Whatever you are doing.
WSet, pixmapWindow
Erase
XYOUTS, StrTrim(j,2), 0.5, 0.5, Alignment=0.5, /Normal
WSet, displayWindow
DEVICE, COPY=[0, 0, 25, 25, 0, 0, pixmapWindow]
ENDFOR

Cheers,

David
