Passing or reference to a subroutine

cosmicperl has asked for the wisdom of the Perl Monks concerning the following question:

Hi All,
I have a few sub routines that take a list of data including refences to hashs and arrays. This is great when the hashes and arrays are variable, but sometimes they are short constants. I'd like to be able to put them in one line so that:-

my @array = (item1,item2...);
my %hash = (key=value...);
&mysubroutine(\@array,\%hash);
[download]

Becomes something like (this example doesn't work hence my asking):-

&mysubroutine(\(item1,item2),\(key=value));
[download]

Thanks in advance

Use `[]` to create a reference to an anonymous array and `{}` to create a reference to an anonymous hash. See perldoc perlreftut. `some_sub(['foo','bar',baz'], { key1 => 1, key2 => 7 });` [download] P.S. Why are you putting `&`'s on your subroutines? That's slightly odd (even though, as I understand it, the Llama recommends the practice of always using the `&`) duff	[reply] [d/l] [select]

You can do it like this: `mysub( [ 'item1', 'item2' ], { key1 => 1, key2 => 2 } );` [download] The `[]` brackets create a reference to an anonymous literal array. And `{}` brackets create a reference to an anonymous literal hash. The way you were trying to do it doesn't work because `\(item1, item2)` is the same as `( \item1, \item2 )` Dave	[reply] [d/l] [select]

For some reason I was putting a \ in front. God knows why. Thanks for the help.	[reply]
