DEFCONST_INTERNAL replacement in 2.9.7+ and later ?

[Muthiah Annamalai]

Hello there,
What is the proper replacement for DEFCONST_INTERNAL macro
that has been deprecated in the present Octave? I cant seem to use
the DEFUN() macro and manage it to load in the interpreter.

All I want is,  to be able to define constants for use within the
interpreter; i.e to do  the C-equivalent of
#define  MY_OCTAVE_VARIABLE 10

in Octave.

Please help.
Regards,
Muthiah
