Re^3: printing all elements of arrays

what does the print map state?

Okay,

print join("\n", @array), "\n";
[download]

says "Stick a newline between each element in @array, return that as a string, print it, and print a newline at the end." On the other hand,

print map {$_ . "\n"} @array;
[download]

says "Build a list whose elements are the elements of @array with "\n" appended to them, then print that list."

what perldoc can I read about the map call?

You can read about any function with perldoc -f func_name.

Here is another way to print the elements of an array on separate lines, using the `$,` variable (see perlvar: `#!/usr/bin/perl use strict; use warnings; my @array = (1..10); local $, = "\n"; print @array;` [download]	[reply] [d/l] [select]
