The "Use of unitialized value in concatenation... blah, blah" error may be because of the way that you are populating the array from the file. Or maybe it is because $myString isn't initialized before the concatenation and you are using warnings.

It would be good if you post the code you are using to populate the array from the file, and how you are referencing the array elements.

split may produce a leading undefined value, or a trailing undefined value depending on how you are trying to split the data in the file.

Please post the code that doesn't work.
