I took the change and also updated the documentation so hopefully it will be more clear in the future how to use it.

It is weird that the previous documentation says that it should be a struct while the source expects a string. Maybe a better fix would have been to change the source to accept a struct rather than change the documentation?

Thanks for the explanation and the fix for the deprecation warning in relation with symbol_table::varref() in rev 12544.
I think this bug can be closed, but I am apparantly lacking the rights to do so.

Looking at the source, I found what it's actually supposed to be doing. It works, but the syntax is very non-canonical, and instead of passing the arguments, you must pass the name of the arguments

octave-cli-3.8.0> s.a = 1;
octave-cli-3.8.0> b = 2;
octave-cli-3.8.0> packfields("s", "b")
octave-cli-3.8.0> s
s =

  scalar structure containing the fields:

    a =  1
    b =  2

Hi,
I wanted to try out packfields, but all I can get from it is an error message:
octave:1> s.a = 1
s =

  scalar structure containing the fields:

    a =  1

octave:2> b = 2
b =  2
octave:3> packfields(s, b)
error: octave_base_value::convert_to_str_internal (): wrong type argument 'scalar struct'

This is with both 3.6.4 and 3.8.
