RE: [SYSTEM21] Change System for test env.

["Chris Tringham" <ctringham@xxxxxxxxxxxxxx>]

Incidentally, this is something that has been tidied-up and rationalised
in Aurora.  There is now a new 'application' that controls all the
subsystems and background jobs, and one set of functions for starting
and stopping jobs.  It should now be easier to set up test subsystems.

We found one rather strange problem with it, namely that if you start
your background jobs from the blank environment and then try and stop
them from the default environment, the control program dumps.  Geac have
apparently put in a fix to prevent you submitting the background jobs
from the blank environment, but have no plans to put a similar
restriction in the interactive programs. 

Obviously it's easy to avoid this happening, but I had always understood
that the blank and default environments should be identical (apart from
modification libraries if you have them), and it shouldn't matter which
one you use.  I have always used the default environment, but I know
some Geac consultants who normally use the blank environment.  

Is the blank environment just something that exists but which you are
not supposed to use, or do some people use it deliberately?  Would you
expect the system to work normally if you selected the blank
environment?
