Re: %hash print output formatting question

It's right in the docs :)

"If you evaluate a hash in scalar context, it returns false if the hash is empty. If there are any key/value pairs, it returns true; more precisely, the value returned is a string consisting of the number of used buckets and the number of allocated buckets, separated by a slash."

The OP can avoid evaluating the hash in scalar context by changing the dots to commas in the print statement: `sub print_formatted { print "print \%hash with other text:\n"; print "\%hash: " , %hash , "\n\n"; }` [download] For quick dumping of hashes (and arrays, and references, etc.), see also Data::Dumper.

makes perfect sense... Thanks for the tip on using commas instead!! fyi - I'm a big fan of Data::Dumper, but in this case I was being a bit lazy... Thanks again! Life is short, but it's wide -- Chuck Pyle	[reply]

makes perfect sense... I get a little frustrated trying to find things in the docs - I do remember (a long time ago) reading something about the buckets though.... I appreciate you pointing me in the right direction! Life is short, but it's wide -- Chuck Pyle	[reply]
