You didn't give us the full information needed. Where in the script does the problem happen? Moreover, "Uninitialized value" is not an error, it's just a warning.

Without seeing a sample of the input data, we can't really tell what's wrong. See also Short, Self Contained, Correct Example on how to ask a good question with a high chance of getting a satisfying answer.

    The input data is just standard CSV files full of data.

    I get this chunk of 'warnings' repeatedly;

    Use of uninitialized value $listenerName in numeric eq (==) at C:\Strawberry\perl_tests\CSV_Parser.pl line 99.

    Use of uninitialized value $port in numeric eq (==) at C:\Strawberry\perl_tests\CSV_Parser.pl line 112.

    Use of uninitialized value $channel in numeric eq (==) at C:\Strawberry\perl_tests\CSV_Parser.pl line 125.

    Use of uninitialized value $name in exists at C:\Strawberry\perl_tests\CSV_Parser.pl line 142.

      same for 
      length[$Depth]
length[$Persistence]
length[$Description]
