OK. Understood.
Under octave2.1, the equivalent was:
INFO_PROGRAM = "info-emacs-info";
It thus changed from a variable to a function.
Now, there are some discrenpancies into the documentation:
octave2.9-info states:
`--info-program PROGRAM'
Specify the name of the info program to use. The value of PROGRAM
specified on the command line will override any value of
`OCTAVE_INFO_PROGRAM' found in the environment, but not any
commands in the system or user startup files that set the built-in
variable `INFO_PROGRAM'.
and
`INFO_PROGRAM'
*Note Getting Help::.
Default value:
`"OCTAVE-HOME/libexec/octave/VERSION/exec/ARCH/info"'.
in E.4 Using the Emacs Info Reader for Octave
You can use either `plain' Emacs Info or the function `octave-help'
as your Octave info reader (for `help -i'). In the former case, set
the Octave variable `INFO_PROGRAM' to `"info-emacs-info"'. The latter
is perhaps more attractive because it allows to look up keys in the
indices of _several_ info files related to Octave (provided that the
Emacs variable `octave-help-files' is set correctly). In this case,
set `INFO_PROGRAM' to `"info-emacs-octave-help"'.
It seems that some documented variables don't exist anymore (octave2.9.9,
debian testing) : DEFAULT_LOADPATH, INFO_FILE, INFO_PROGRAM, LOADPATH ? OTOH,
things like 'EDITOR' and 'PS1' are now listed as 'built-in functions' ?
