Has anyone here worked with yacas? I'm trying to run it from my program but I can't even get it working from the command line. If I have "1+1;" in a file I get:



aurora:~ chris$ yacas test
[editvi.ys] [unix.ys]
Quitting...
aurora:~ chris$ yacas -f test
[editvi.ys] [unix.ys]
Quitting...
aurora:~ chris$ yacas -pc test
aurora:~ chris$


What am I doing wrong?
