Hi,

Is it possible to set a local variable from within a Closure?

I'd like to do something similar to :

Int wot := 0;
[1,2,3].each |ever| { wot := wot + ever }

But I`m told Variable wot is already defined in current block.

I understand the error, just don't know how to get around around it. I could use a for loop, I`d just rather not!

Steve.

You need to change := to = in your closure. := operator is used only for defining variable, = is use to reassign another value to it.

Hmm, okay. So I didn't get fundamental assignment operator:

Int wot := 0;
[1,2,3].each |ever| { wot = wot + ever }

Now if only I could delete this thread and pretend I never posted it!

Thanks dluksza - I think our posts just crossed!
