Hi GRASSers

I 've got two questions (which I hope not to be to silly ;-) )

-1-

Is it possible to use r.mapcalc to calculate the minimum, maximum and /
or the average of raster layers with using UNIX wild cards ("*" in my
case) such as:

r.mapcalc max970124=max(a12*970124*)

to calculate a raster layer called max970124 of the maximum of all
raster layers matching "a12*970124".

-2-

Could anyone give me a pointer to an introduction to MAPGEN, please?
I 've found
> User's Manual for MAPGEN (UNIX version): a method of

>                 G.I. Evenden, J.M. Botbol, USGS Open-File Report
> 85-706, 58p.
as a reference, but not as a PS (like some other USGS OF Reports...)

Regards,

	Stephan
