in reply to chunk!

I assume you refer to messages like:
Use of uninitialized value at ./foo.pl line 7, <BAR> chunk 198.
This warning indicates that you used an uninitialized variable at line 7 in your script. The chunk refers to the last chunk just read from filehandle BAR. The chunk number depends on what kind of chunks you read in (default is that 1 chunk = 1 line). You can change what a chunk is by assigning the variable $/.

The chunk part of the warning is meant to help you to find out where you were in the currently opened file when the warning occured.

BAR does not have to be a file, but can also be a socket handle, directory handle etc. (in UNIX everything is a file :-) )

So chunk doesn't say much about what kind of warning/error it is - you use the message for that.

You can use diagnostics to get verbose help for your warning/error messages

#!/usr/bin/perl -w use diagnostics; # Force a warning $foo = 1;
