in thread How can I get the current OP address (akin to PC)?

Thanks for the suggestion. I tried and it didn't work for me.

Here is something that sort of works but doesn't really.

In file /tmp/Devel/COP.pm:

package DB; sub DB { ($pkg, $filename, $lineno) = caller; $COP = 0; local(*DB::dbline) = "::_<$DB::filename"; if (defined $DB::dbline[$lineno]) { $COP = 0 + $DB::dbline[$lineno] ; } }; 1;
And to test it, put in file /tmp/code-test.pl:
#!/usr/bin/perl use B::Concise; sub testit () { my $walker = B::Concise::compile('-basic', '-src', 'testit'); B::Concise::set_style_standard('debug'); B::Concise::walk_output(\my $buf); $walker->(); # walks and renders into $buf; print $buf, "\n"; printf "COP is 0%x\n", $DB::COP; } testit();
Now run as perl -I/tmp d:COP /tmp/code-test.pl

The problem is that the COP address is always the first statement for the line. And what I really want is the one we are currently at which might not be the first COP of the line. Sigh.

[TStanley]: I'm sitting in the airport in Tampa, Florida at the moment, getting ready to head home.
[talexb]: TStanley I'm flying to Vegas in two weeks time. After that flights leaving Vegas and Phoenix are late at night .. I've been hearing that it gets so hot that the air isn't dense enough for planes to take off. Weird. Guess you won't have that problem.
