>> I tried $result = `C:/Program\ Files/GNU\ Octave\ 2.1.50/bin -q >> my_script.m`; but $result is still null.
sorry, in copy and paste I forgot a part of the instruction. The instruction I'm using is: my $output = `"C:/Program\ Files/GNU\ Octave\ 2.1.50/bin/octave.exe -q my_script.m"`; The error I've is: 'C:/Program' is not recognized as an internal or external command, operable program or batch file. I tried to exec a my_script.bat file located in the same directory of octave.exe, just with "echo hello!", and that run fine. I cannot use system("") as I'm working with strict and taint parameters, and this instruction is forbidden. Thanks for any hint.
