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
