in reply to Analyzing Perl Code

Put the following code in a file called: /yourperl/site/Devel/

package Devel::Calls; our $lastsub; sub DB::DB { my( $p, $f, $l, $sub ) = caller(1); return if $lastsub and $sub eq $lastsub; printf STDERR "%s(%u): %s()\n", $f//'unknown', $l//'0', $sub//'unknown', $lastsub = $sub; return; } 1;

And then invoke your scripts with perl -d:Calls

You'll get a trace showing file, line and subroutine name whenever a subroutine is entered, something like:

C:\test>perl -d:Calls 1 2 3 unknown(0): unknown() main::aaa() main::bbb() main::ccc() main::ddd() main::eee() main::fff() main::ggg() main::hhh() main::iii() main::jjj() main::kkk() main::lll() main::mmm() main::nnn() main::ooo() main::ppp() main::qqq() main::rrr() main::sss() main::ttt() main::uuu() main::vvv() main::www() main::xxx() main::yyy() main::zzz() 234

That could obviously be greatly extended, but it may be just what you're looking for.
