the script is a grass python script i made to automate some processing
and fondamentally uses r.mapcalc to perform map algebra e.g:

##
grass.mapcalc("$mapoutfile = abs($inraster)",mapoutfile=outraster+'_oname_'+kf.__name__,inraster=outraster+'_'+ofile.__name__)
##

This beacause the script have an interface generated by grass parser,
and that is the only way I found to have it run in MS Windows (that worked in grass 6.4.3)
also the scrip flawlessly works in linux.

I tried your advice, copied the script in

C:\OSGeo4W\apps\grass\grass-6.4.4\scripts

and made the bat file in

C:\OSGeo4W\apps\grass\grass-6.4.x\bin

but tring tu run it i get this error:

#### grass output:

Traceback (most recent call last):

ore\prompt.py", line 840, in OnItemSelected

"\n\nDetails: %(det)s") % { 'cmd' : cmd, 'det' :
decode(cmderr) }
grass.script.core
.
ScriptError

#### end


thanks, Roy.
