Hi,

Well, Mathematica isn't a clone of another system, whatever that might
be, so you will unfortunatly have to learn to do things the
"Mathematica" way. From what you describe

DeleteCases[yourlist,0,Infinity]

most probably will do what you want, but I'm not sure. You could also
look at the documentation for Cases and Select or Pick which provide
similar possibilities to select parts of a list or array.

hth,

albert
