Anonymous Monk, `print "$_\n" for @array;` Cheers - L~R Update: I love Perl In a short span of time numerous solutions have been provided. For such a simple task as printing the elements of an array - lots of Perl has been used: bare blocks to limit scope The need to use local instead of my on Perl built in global variables printf for flexibility over print Print many with a for loop versus printing once with join Weird built in variables such as $_, $", $/, and $, Let me add a couple more using $\ and map `{ local $\ = "\n"; print $_ for @array; } or print map {$_ .= "\n"} @array;` [download]	[reply] [d/l] [select]

Limbic~Region Re this snippet: `print map {$_ .= "\n"} @array;` As the OP is obviously a beginner, I believe that the proviso to this, namely that it changes `@array` (adding a newline to each element), should be clearly stated. dave	[reply] [d/l] [select]

dave, You ever start typing a word and end up automatically type something else out of habit? That should have been: `print map {$_ . "\n"} @array;` [download] Thanks - L~R	[reply] [d/l]

`printf "%s\n",join("\n",@array);` [download] just that simple. Peter @ Berghold . Net Sieze the cow! Bite the day! Nobody expects the Perl inquisition! Test the code? We don't need to test no stinkin' code! All code posted here is as is where is unless otherwise stated. Brewer of Belgian style Ales	[reply] [d/l]

And here is another that uses the `-l` command switch (and that's dash elle, not dash one). `#!/usr/bin/perl -l my @array = 0..9; print for @array;` [download] jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]

Why not simple over fancy?? my @people = ('fred', 'bill', 'charley'); foreach my $person (@people) { print "$person\n" };	[reply]

Because this is Perl and, repeat after me, "There Is More Then One Way To Do It"	[reply]
