File Compare and Create New File with Diff

I need to compare File A with File B and create FILE C with the difference record only. What I mean is File A has 3 records and File B has 4 records, so FILE C will only have 1 record (becuase that record is in FILE B and not in File A). Hope I am making sense. The data layout is that each data element is within double quotes and each field is seperated by a comma. In the example below after the second name there is a double quote and 3 commas, the first comma is the field seperator and the other 2 commas are for fields that there is no data, hence the commas.

File A

"00000000155","JOHN","SMITH",,,"1944-06-03",
"00000001166","SMITH","JOHN",,,"1947-24-01",
""00000002189","BOB","SMITH",,,"1947-03-04",

File B

"00000000155","JOHN","SMITH",,,"1944-06-03",
"00000001166","SMITH","JOHN",,,"1947-24-01",
""00000002189","BOB","SMITH",,,"1947-03-04",
""00000002263","SMITH","JOHN",,,"1948-02-24",


I am not sure what uniz command to use, I haev done some reading and it looks like I can use the diff command or maybe even teh awk command. If someone can provide assistance here , I would be greatly appreciate it.

Sincerely

File::Slurp::WithinPolicy(3pm)				User Contributed Perl Documentation			    File::Slurp::WithinPolicy(3pm)

NAME
File::Slurp::WithinPolicy - Applies filesystem policies to File::Slurp SYNOPSIS
use File::Slurp::WithinPolicy qw(:all); my $text = read_file( 'filename' ); my @lines = read_file( 'filename' ); write_file( 'filename', $text ); append_file( 'filename', $more_text ); overwrite_file( 'filename', $text ); my @files = read_dir( '/path/to/dir' ); DESCRIPTION
This provides the File::Slurp interface within a policy defined by File::Policy. By default, File::Policy is a no-op and this behaves identically to File::Slurp. System administrators may want to override the default File::Policy implementation to enforce a local filesys- tem policy (see File::Policy). FUNCTIONS
read_dir See "read_dir" in File::Slurp read_file See "read_file" in File::Slurp write_file See "write_file" in File::Slurp append_file See "append_file" in File::Slurp overwrite_file See "overwrite_file" in File::Slurp EXPORTS
By default, nothing is exported. The ":all" tag can be used to export everything. Individual methods can also be exported. SEE ALSO
