Octave has several examples of oct-file code in the directory etc/examples/.
These can be compiled with *mkoctfile* and used by the interpreter.

However, the file *globaldemo.cc* no longer compiles and instead fails with
the following messages:

mkoctfile globaldemo.cc
globaldemo.cc: In function ‘octave_value_list
Fglobaldemo(octave::interpreter&, const octave_value_list&, int)’:
globaldemo.cc:15:29: error: ‘class octave::symbol_table’ has no member
named ‘global_varval’
   15 |   octave_value tmp = symtab.global_varval (s);
      |                             ^~~~~~~~~~~~~
globaldemo.cc:22:10: error: ‘class octave::symbol_table’ has no member
named ‘global_assign’
   22 |   symtab.global_assign ("a", 42.0);
      |          ^~~~~~~~~~~~~


Apparently this isn't new.  I went back through versions of Octave to 8.4.0
and I still get this error.
