Hi listendohg,

However, even if I call "my @array4 = 0;" before the loop begins, I keep getting an error when I try to do any downstream work which reads "Use of uninitialized value within @array in join or string".

You are declaring the array with an element, 0. So when you later go through the elements, the first one is zero. If your code at that point is testing for truth, it will be an uninitialized value.

Declare your array so it contains an empty list instead: my @array;.

When you say "even if I call "my @array4 = 0;" before the loop begins" this indicates that you may not be using strict in your program. You certainly should declare a variable outside a loop (not inside it) if you wish to use it after the loop.

Finally, if you are storing a hash table as a string and later retrieving it for use again as a data structure, you may want to use JSON.

Hope this helps!


The way forward always starts with a minimal test.
