Hallo!
Yes, at least when I made this alias folder iemmatrix it did work quite well. I also made aliases for iemlib and some more stuff from iem ... so I don't see a problem ... (I agree that maybe in future we should avoid aliases)
what is wrong with aliases? why should they be avoided? do you prefer [f] or [float]?
Ok I have to correct myself: maybe one should use it with care and only if it makes sense ... ;)
LG Georg
