[GRASS5] problem in Grass 5.3

[Michael Barton]

I've been using Grass 5.3 for a couple weeks now on a Mac OSX/BSD G4 
and overall it has been extremely stable. Last night, I ran into the 
first bug so far. I needed to georeference a set of points representing 
cesium magnetometry data from an archaeological site. To do this, I 
converted the site file to a vector point file, and the vector point 
file to an ascii vector point file. So far so good.

However, when I tried to use v.transform I ran into problems. First, 
the documentation describes this as a module to transform binary vector 
files, but the TCLTK interface wants ascii vector files. The command 
line interface also seems to want ascii files. In the TCL interface at 
least v.transform only looks for files in the dig.ascii folder (correct 
for ascii files of course), but won't find them unless they are copied 
into the dig folder (i.e., binary vector files).

Second, when I ran it with 9 points for coordinate transformation, it 
crashed with a maloc and out of memory error. I reduced it to 4 points 
and it ran.

Finally, it produced the header of an ascii file output (in the dig 
folder) but not the rest of the file. It DID produce a file of 
transformed coordinates in the dig.att folder.

  I had to use this attribute file to paste into an excel spreadsheet, 
along with the magnetometry values from the sites file, which I then 
exported to CVS and imported into s.in.ascii.

A very roundabout method. Anyway, v.transform seems to be confused 
about what kind of files it is using for input and output.
