in thread How do you sort keys of a hash in descending order and print 3 per line?

I received this message: Argument "t" isn't numeric le (<=) at c:\users\michael\desktop\lab7-startup.pl line 119, <STDIN> line 17. Any idea why?

I received this message: Argument "t" isn't numeric le (<=) ... Any idea why? Because you've mis-copy/pasted the code. I can copy/paste the exact code posted by bangor above and run it with warnings and strict enabled, and no complaint from Perl. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l]

My code looks exactly like the one you suggested.	[reply]

`c:\@Work\Perl\monks>perl -wMstrict -e "my %accounts = ( tom => \"BigApple\", tom2 => \"BigApple2\", tom3 => \"BigApple3\", tom4 => \"BigApple4\", tom5 => \"BigApple5\", tom6 => \"BigApple6\", tom7 => \"BigApple7\", ); my $counter = 1; for my $userID (reverse sort keys %accounts) { print \"$userID\t\"; print \"\n\" if $counter++ % 3 == 0; } " tom7 tom6 tom5 tom4 tom3 tom2 tom` [download] There's a lot of command line "noise" from having to escape all the double-quotes for Windose, but that's exactly the code I ran and its output: otherwise exactly the code bangor posted. What is the code you are running? Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]

He's a monk, not a clairvoyant! Please post the relevant line of code that the error is pointing you to :-) The way forward always starts with a minimal test.	[reply]
