We can't import more than 49 files

[R. Joe Brandon]

Malcolm,

Whenever I have had to do large sets of maps I use a syntax in my shell  
such as:

r.patch input=All.Prehistoric.Sites,395-573.p.poly,400-568.p.poly,408-607.p.poly
,409-597.p.poly,410-606.p.poly,412-601.p.poly,414-583.p.poly,414-601.p.poly,414-
609.p.poly output=patch1 

etc... and then patch the maps together.  Is this the style you are 
suggesting or would you suggest that they have an actually variable such as


r.patch input=$
