[GRASS-dev] Some doubts

[Roberto Antolin]

Dear all,
I have some questions that I would like to resolve.

This summer I was discussing with Markus about extern variables. He told 
me that there were some compilation problems and it would be better not 
to use them. But I saw that they are used all over GRASS. So, which is 
the point with them? Should they be declare in an especial way?

There is a second question about the database and driver module's 
options. When I wrote my modules (v.surf.bspline, v.outlier and 
v.lidar.*) I needed the database and driver information. I decide to ask 
the user for them in the case he/she wants to use other than the default 
values. But, is better to ask the user for these parameters within the 
module, or maybe is better to use the default values?

A third final question: To show the progress of the module, is actually 
needed?

Thank you a lot,
Roberto.
