In ANSWERS, the program "crashes" if the aspect of any cell containing the
channel does not correspond with the channel itself.  To identify the row
and column #s, and the aspect of any specific cell in an ANSWERS ELEMENT
map, you can use either or all of these programs: 

d.what.rast  [GRASS Main Program]
d.rast.num   [GRASS Alpha-test Program]
d.rast.arrow [GRASS Alpha-test Program]

Additionally, you can use d.rast.edit [GRASS Alpha-test Program] to edit 
the aspect of any specific cell.  

**None** of the above, however, are script programs.  

Hope these will help.  Good luck!!!
