Activate debug printing by setting the environment symbol TOCHNOG_DEBUG to yes.

Printing can be limited by setting the following environment symbols:

environment symbol purpose
TOCHNOG_ELEMENT element_number Printing for specific element only.
TOCHNOG_ICONTROL control_number Printing for specific control index only.
TOCHNOG_ITERATION iteration_number Printing for specific iteration only.
TOCHNOG_NODE node_number Printing for specific node only.
TOCHNOG_ROUTINE routine_name Printing for specific routine only.

You also can set the environment variable TOCHNOG_REPORT_ROUTINE. Then tn reports the routines it passes.

After a calculation, the entire database can be printed by using control_print_database index -everything. This prints, besides the normal user variables, also internal variables.
