Re^2: processing key value pairs of a hash

1) "perl -w" in the she-bang line and "use warnings" are pretty much the same thing (won't hurt of course :-)

Here is the difference, according to warnings:

The warnings pragma is a replacement for the command line flag -w , but the pragma is limited to the enclosing block, while the flag is global. See perllexwarn for more information.

Don't get your posting... I know there is difference that's why I said "pretty much the same" and not "exactly". For his case (as he does not seem to want to turn warnings off for a particular lexial scope) it won't make a difference. But ok: 6) Don't use -w, always use warnings so you can turn them off again.

The reason for my posting was to provide additional, specific information -- in the form of a link to the official Perl documentation -- as to the differences between `-w` and warnings, mostly for the benefit of the OP (or anyone else who is interested). It is good that you brought this to the attention of the OP.	[reply] [d/l]
