[GRASS-user] Unable to use Command Line Access to GRASS-GIS

[Artur Bercik]

Dear Vaclav Petras:

Thanks for your answer, and sorry for cross posting.

I am thinking of accessing the grass command line through
"C:\OSGeo4W\bin\grass70.bat" using  python subprocess.call

Are you familiar with this one?
