[GRASS-user] r.out.bin fails consistently on Windows 10

[Dr Jonathan Ball]

Hi List,

I am trying to use r.out.bin.  I initially tried it from within QGIS and 
have moved to using a standalone version of GRASS 7.2 on Windows 10 (64 
bit).  I have tested with a variety of rasters and I consistently get 
the same error message:  "Unable to create file <output_filename>" 
whether I use default settings or tweak the optional parameters.

Since r.out.bin is apparently based on r.out.ascii, I experimented with 
that utility and it works well for me with no errors.  I can do a 
'round-trip' (export to ascii and then re-import from the output file).  
So, the problem seems to be specific to r.out.bin.

Before I log a bug report, can anybody confirm whether this utility 
actually works in Windows or offer any pointers as to what I might be 
doing wrong?

Many thanks

Jon
