Now, below program works.. but I still see some uninitialized values
Here's what I mean. I am running a below code against file that has SIP message, which has various format according to what message and what situation. When I run below code against entire file, it works but exception of some areas where I don't get my value initialized and I suspect that when it goes through line (14-16), it doesn't find the match? and it skips out as I see error message 
Use of uninitialized value at ./perl.m line 32, <FH> chunk 1.
Use of uninitialized value at ./perl.m line 32, <FH> chunk 1.
Use of uninitialized value at ./perl.m line 32, <FH> chunk 894.

but line 17 through 38, it recognize as entire record and process what it needs to.. What am I missing in line 14 through 16 that my regular expression is not matching(I want it to match so that it skips out(next record). 
#!/usr/bin/perl -w

my $ncb = $/;
