Re: Use of uninitialized value at?

In versions 5.6 and later, you can use no warnings 'uninitialized' to suppress that error. In prior versions, you can localize a warnings handler ($SIG{__WARN__}) to suppress that error. Otherwise, you have several options.

Use a map block to set each element in the array to a null string if it's not defined.
Skip undefined elements in the loop.
Turn undefined elements into blank strings within the loop.

And in versions before 5.6 you can use the $^W global. eg: `{ local($^W) = 0; # suppress warnings ... your code here ... }` [download]	[reply] [d/l]
