Split output to screen and to file about njoy21

Too vague to act on. What do you want sent where?

NJOY2016 would print a line at the beginning of every module call. In addition, warnings, messages, and errors would also be printed. For example, here is the output from Test01 when run with NJOY2016:

It's not a lot of information, but enough information to know that the calculation is proceeding. The messages that are printed are those that are most important for the user to know.

If I can understand the fortran correctly, there is a file referred to as nsyso (from mainio.f90 and opened in main.f90) that is the output file on disk. To this file is written everything. Similarly, another "file" is opened and referred to as nsyse; What is written to this, is written to the screen.
