Hi again
I will put my question in a different way.
What I do now is to read the data directories/file names in a loop
and then I start the calculation. The calculation is performed inside a
Do, where I generate my tables, save them in the appropriate
directories, and generate the graphics and save them also in different
directories. That works, but this is not a well-organized procedure
because I have all the calculations inside a very large Do loop, that
means that my notebook is almost a single large Do cell.
I think it would be much better if I could have my calculation
inside another notebook and if I call this notebook inside the Do loop.
My first try was to have a notebook to read the data file and
directory names and the call a second notebook. In this notebook I have
part of my calculation, rather documented and it called the last
notebook which would finish the calculation and return to the next data.
In the front end I manage to call the second notebook but it was only
opened, not evaluated, I have to evaluate it manually. Perhaps the
problem does not involve batch, but rather one notebook calling and
evaluating another notebook.
Thank for your your fast help.
Regards
