Malcolm, I've tried 'rehash' in my GRASS window and there doesn't appear
to be any change - certainly not the changes I'd expected !
I'm no expert on Unix - basic level really - but OK on 'C'. What has me
puzzled are the two sorts of ps.map file - the 'file' command shows both
the 24K one, which isn't changed by the recompile, and the large one
200+K, which is changed, as being 'sparc demand paged dynamically linked
executable'.
What has me even more confused - if that was possible 
- is that I
recompiled the modified version of ps.map 'do_vector.c' that you sent me
in what I thought was the same way and that worked ??
Thanks again for any help,
Steve Culshaw
