Hello,  
I’ve been looking at the array stuff in the Noobkit, but I can’t seem  
to find how to insert another entry in the array… Pretty much, I’m  
going to be iterating through stuff and catching some things and adding  
them to an array. I want to always add to the end of the array… In  
stuff I’ve seen, you must define an index.

Any suggestions?

Thanks,

- Jeff

@a = Array.new  
@a.push “item1”  
@a \<\< “item2”  
@a.join(",") =\> “item1”, “item2”

that’s not correct. This is what it does:

> > a = Array.new  
> > =\> []  
> > a.push “item1”  
> > =\> [“item1”]  
> > a \<\< “item2”  
> > =\> [“item1”, “item2”]  
> > a.join(“,”)  
> > =\> “item1,item2”
