build array

I would like to build an array without including any information that has been set to 0.  For example the numbers: 25,13,63,42,0,8,2 would be an array such as this:

25

13

63

42

8

2

If I use the classic build array function, the 0 would be passed because I am taking the numbers from local variables.  It would look like this:

25

13

63

42

0

8

2

Any help would be appreciated
