[GRASS-user] r.li help

[William Kyngesburye]

I did a little crude debugging yesterday (G_message) and found it  
failed for me in daemon.c, line 626 / nextArea()

     else {
	return next(g, m);
     }

But all this tells me is that at this point the mask name is missing,  
not where it was lost.

I didn't have more time to poke around more.

[Trillian]  What are you supposed to do WITH a maniacally depressed  
robot?

[Marvin]  You think you have problems?  What are you supposed to do if  
you ARE a maniacally depressed robot?  No, don't try and answer, I'm  
50,000 times more intelligent than you and even I don't know the  
answer...
