As a one-time PL/1 programmer (we got our record layouts from you COBOL guys), I'd eschew the record structure you want to use.
ikegami gave you a great solution; I'd suggest tweaking
my %Employee_Rec;
@Employee_Rec{qw(
Emp_No
Emp_Lname
Emp_Fname
Emp_SSN
Emp_DOB
Emp_aka
)} = $csv->fields();
print "$Employee_Rec{Emp_No} \n";
print "$Employee_Rec{Emp_Lname} \n";
print "$Employee_Rec{Emp_Fname} \n";
print "$Employee_Rec{Emp_SSN} \n";
print "$Employee_Rec{Emp_DOB} \n";
print "$Employee_Rec{Emp_aka} \n";
to
my ( $Emp_No, $Emp_Lname, $Emp_Fname, $Emp_SSN, $Emp_DOB, $Emp_aka
+) = $csv->fields();
print "$Emp_No \n";
print "$Emp_Lname \n";
print "$Emp_Fname \n";
print "$Emp_SSN \n";
print "$Emp_DOB \n";
print "$Emp_aka \n";
You gain nothing from storing the information in a hash (unless you were going to make a Hash of Hashes, keyed on the Employee Number). Prefacing the fields with Emp_ indicates the fields are related.
