Thanks for pointing that out, but that was just a copy and paste mistake, not what my actual question is about.	[reply]

I think he meant to demonstrate that you do not need `\$` (or `$$`) to access the data you have described. However, if you want to create a reference to that single piece of data then you do indeed have to use the prefix `\` because that's exactly what that prefix does. There are also other ways to create references to data, such as `{}` and `[]`. References are described in `perldoc perlref` If this does not answer your question, maybe you need to provide a little more context to help us understand why this does not solve your problem? -- FloydATC Time flies when you don't know what you're doing	[reply] [d/l] [select]

I thought your actual question was about a \. Please note my print statement does not need the \ to work correctly. Perhaps I am misunderstanding your question. Please provide an actual runnable program that shows a failure when the \ is not used, and success when the \ is used, and we can proceed from there.	[reply]
