Hi Monks,
Please do the following:
1. Download Devel::Trace and install it.
2. Take the code below into a file.
print "line 1\n";
# line 2bug
print "line 3\n";
print "line 4\n";

[download]
3. Execute "perl -d:Trace your_file.pl"

See that after the line "# line 2bug" the file name found by caller() in Trace.pm is the "bug" string.
>> /usr/local/aig/common/db/Development/scripts/pf/script1.pf:1: print
+ "line 1\n";
line 1
>> bug:2: print "line 3\n";
line 3
>> bug:3: print "line 4\n";
line 4

TIA,
shushu
