Thought of trying use diagnostics;?
Also consider moving those arrays to anonymous arrays in a hash.

# List all search criteria
my @search = ( 'CCFN\d+NT','CCFN',
               'EBGFN','EBG',
               'PRFN','PR',
               'BLSTDGG','BLSTDG','BL');

# Build an index of the fields they correspond to
my %index = map{ $earch$_ => $_ } (0..$#search);

# Make a hash to store the results
my %results = map { $_ => [] }@search;

# Make a generic regex, for one pass.
my $regex = join( '|' map{"($_)"}@search);

# Blah blah split and stuff. 

# Use the bracketed results of the regex to store data.
m/$regex and push @{$results{$1}}, $line[$index{$1};

print Dumper \@results{@search};
