The problem with using monitors on native Windows isn't the graphics,
it's the client-server communication.

OK: hopefully I won't bother the list any longer on X-monitors.<br>

<pre wrap="">If the environment variable GRASS_RENDER_IMMEDIATE is set to TRUE, PNG
or PS, all d.* commands write graphics directly to a file, without
using a monitor.
The filename, format and dimensions are set by environment variables,
as described at:

All of the functionality of the PNG and PS drivers is available in
this way.

This works fine in my Cygwin/grass6.2.2 installation, although the
GRASS_PNG_READ variable does not seem to be available in grass6.2

thing suggested by Paul wouldn't work.<br>
<br>
Trying the same with native winGRSSS 6.3.0 RC5 is less of a success:
(1) no way to set environment variables via the GUI Output - GIS.m
window; (2) not able to start GRASS via cmd.exe as suggested at<br>
<a class="moz-txt-link-freetext" href="http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status">http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status</a><br>
<br>
by typing the following at the cmd.exe prompt:<br>
<blockquote>C:\grass63RC5\bin\grass63.bat -text<br>
</blockquote>
I get the output below:<br>
<blockquote>Welcome to GRASS 6.3.0RC5 (2008)<br>
<br>
GRASS homepage: <a class="moz-txt-link-freetext" href="http://grass.itc.it/">http://grass.itc.it/</a><br>
This version running thru: Windows Command Shell (cmd.exe)<br>
When ready to quit enter: exit<br>
Help is available with the command: g.manual -i<br>
See the licence terms with: g.version -c<br>

<blockquote>"cmd.exe" non è riconosciuto come comando interno o esterno,<br>

(the Italian error message would sound more or less like: "cmd.exe" is
not recognized as an internal or external command, an executable
program or a batch file.)<br>
<br>
Thanks again for your time and insights,<br>
