I have installed octave on an old Linux system that I cannot upgrade. I tried installing 3.03 but the gnuplot version was not recent enough so I went to 2.1.73. This version compiles but I need to specify the --disable-readline flag in ./configure. Once at the octave command line, a minor inconvenience is that Up-Arrow does not recall the most recent commands. Instead it displays [[^A. I was wondering if this is a readline issue? Is there a way to modify the key bindings in an Octave setup file?
