Changeset 130 for palm/trunk/DOC/app/chapter_4.3.html

DVRP output modifications:

• The user can now visualize user-defined quantities using dvrp.

data_output_dvrp calls the new user_interface subroutine
user_data_output_dvrp in case of unknown variables (CASE DEFAULT).

• Two instead of one digit are allowed to specify isosurface and slicer

variables with the parameter mode_dvrp.
