Need Help??

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

I have a method called func1
sub func1{
....

...
return ($a,$b);
}

Now I want a one liner so that I can use the arrayrefs returned from that method

I can do like this

@a=func1($a,$b);

and use \@a any where I required.
But I dont want this instead I want someway to use like \@func1();
Can anyone suggest what shud I do.

How about `[ func1( $x, $y ) ]` [download] You could also modify your function to return an arrayref instead of an array...	[reply] [d/l]

I would return an arrayref instead `sub func1 { # do some stuff return [$a, $b]; }` [download] Then you can do stuff like `$ref = fuc1(); #or @ref = @{func1()};` [download] Hope that helps ;)	[reply] [d/l] [select]

`sub func1{ .... ... return ($a,$b); }` [download] Now I want a one liner so that I can use the arrayrefs returned from that method Am I right to assume $a and $b are arrayrefs already? If yes then something like the following may work for you `my ($aryref_a, $aryref_b) = func1();` [download] RL	[reply] [d/l] [select]
