[GRASS-user] temporary files in a Python Script with mapcalc

[António Rocha]

Greetings

I'm doing some image processing python script with requires the 
calculation of many "intermediate" rasters. for example:
x=a+b+c
alpha=x-(b^gama)
y=c*alpha+b

One possibility is integrating all of it in one expression but I'm 
afraid of having some "minor" error in expression so I prefer to 
separate the calculation.
My question is: how can I use temporary files to store x  and alpha 
value? Or I should create normal rasters and, at the end, delete them?

Thanks
Antonio
