As you've seen that works, or you can also set the environment variable
GRASS_WISH to wish85.exe and that should also work. If you don't like
setting environment variables in Windows you can edit the line containing
GRASS_WISH in grass63.bat (the startup script) to achieve the same result.

SWBD files but when I call the modules "r.in.srtm" or "v.in.e00" through the
menu, they crash telling me that the « child process exited abnormally ».
This happens also with the "Terra ASTER" and "SPOT NDVI" ones for example,
while others, like "Binary", seem to work fine.

r.in.srtm and v.in.e00 are shell scripts and will not run on a normal
Windows installation. You need to install a Bash shell environment if you
want to use them - most people use MinGW and Msys for this. Then you need
to make sure the GRASS_SH environment variable is set to the location of
your sh.exe or bash.exe shell, and also make sure that the MinGW and MSys
bin directories are in your PATH. Again, there are example lines you can
edit in grass63.bat if you want to set this up without editing Windows
environment variables directly.

> If I use QGIS to call the module "r.in.srtm" it doesn't crash, but when I
specify a compressed (or even uncompressed) SRTM file (without the
".hgt.zip" extension), it tells me « "unzip" and "file" are required, please
install them first ». For "v.in.e00" it tells me « 'avcimport' program not
found, install it first ».

All this is telling you that QGIS has partly set up the required Unix
shell environment for you to run those scripts (r.in.srtm/v.in.e00) but
not all the Unix commands you need are available on your system. Check
first that unzip.exe and file.exe really aren't there in your Msys or
Mingw directories - they might be there but just not in the PATH. If not
you may be able to get them from http://gnuwin32.sourceforge.net/,
although I'm not sure exactly which package they'd be in. I'm not sure
where you'd get avcimport from.

Hope this makes things clearer; I'm not sure if it will get you anywhere
though.

Thanks a lot Paul. I'll try this installing MinGW or Msys, as I thought it
wasn't necessary with the native win version.
I'll keep you posted.

Greetings.
