[GRASS-user] How to embed a grass script (for example v.db.addcol) into a Pythonscript on windows?

[Sonja Jankowfsky]

I made some further tests:

in C:\Windows\system32\cmd.exe
C:\GRASS-4-SVN\bin\v.in.ogr.exe
result: L'ordinal 284 est introuvable dans la bibliothèque de liaisons 
dynamique SSLEAY32.dll.
(call to v.in.ogr works fine in a pythonscript run in Eclipse, but not 
run in the windows command line)

C:\GRASS-4-SVN\bin\v.db.addcol.bat
result: '""' n'est pas reconnu en tant que commande interne ou externe, 
un programme ex‚cutable ou un fichier de commandes.

in GRASS Command Line
GRASS 6.4.0svn (YzeronEPSG)> C:\GRASS-4-SVN\bin\v.in.ogr.exe opens the GUI
same for .... v.db.addcol.bat

I have no idea where the error with the SSLEAY32.dll comes from, but my 
conclusion for the v.db.addcol is, that:
inside GRASS there is something installed to execute the bat files with 
shell scripts. Do I have to add this "something" to my environment 
variables of my windows machine in order to be able to run the bat files 
with my windows command line? What's this "something", Msys?
Do I have to be inside GRASS to run the pythonscripts?
Thanks for any ideas,
Sonja
