process which needs them. You have to invoke the GRASS modules in the BAT
script which is setting the variables or in the subprocess called from the
BAT script.

Other possibility is to set the variables in the MS Windows system settings
but this limits you to one particular GRASS installation (others might be
broken) and it is not as safe (concerning stability of other installed
programs) as just setting the variables for a given process.

In other words, the variables are inherited by subprocesses, so starting
the BAT script just sets the variables for the BAT process but other
processes invoked later are independent.

Running GRASS GIS modules outside of the GRASS session is not trivial, so
it is great that you asked for help.

Just try to avoid cross posting next time. Speaking about that, would
somebody (including Arthur) mind to answer the question on GIS SE?
