Function Reference
— Built-in Function: val = info_program ()
— Built-in Function: old_val = info_program (new_val)

Query or set the internal variable that specifies the name of the info program to run. The default value is "octave-home/libexec/octave/version/exec/arch/info" in which octave-home is the directory where all of Octave is installed, version is the Octave version number, and arch is the system type (for example, i686-pc-linux-gnu). The default initial value may be overridden by the environment variable OCTAVE_INFO_PROGRAM, or the command line argument --info-program NAME.
