Re^8: Pointers and References

That's because 1,2,3 are literals which are read only. Use variables (sic) and you can change them in the loop. ;)

It took me a few times to understand this line based on the examples given further below but now this makes sense!

Perl is aliasing in for loops. So `$x = 42` is as useful as `1 = 42` HTH! :) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

So $x = 42 is as useful as 1 = 42 I don't understand this statement. I can see where an expression like `$x = 42` might be useful, but `1 = 42` can't possibly be useful because it won't compile. Update: Or do you mean "if `$x` is aliased to a literal value (e.g., 1), `$x = 42` is equivalent to `1 = 42`"? (Update: And specifically WRT to the `for`-loop here? I didn't look back far enough. :) Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
