This is a question regarding the use of the 
r.combine command.

Can more than two maps be used as input for r.combine?

We have tried several combinations to accomplish the
following English desired operations:

  MapTest and 
	Grous 1 to 2 from ChinaIsland
	and
	Groups 3 to 4 from IrrigationSuitability
	and
	Groups 5 to 6 from WetlandSuitability

For example, here one version of r.combine 
command line input:  (we spare all the things we have attempted  :-)  )

(NAME TestMap 
  (AND (GROUP 1 2 (China_Island)) 
	(GROUP 3 4 (IrrigationSuitability)) 
	  (GROUP 5 6 (WetlandSuitability))
  )
)

Note: the above was split for readability, 
	  it was actually a continuous line)


Thanks

Sincerely Rolando Vadas and Steffen Meyer
