Re^2: printing arrays

Once you have the list that you want to print; you don't need to use ~~a join~~ join, instead you can just print it with $, set appropriately. $, is also known as $OFS and $OUTPUT_FIELD_SEPARATOR; use perldoc perlvar. ~~This can be much more efficient even with small lists.~~

my @arr = ( 1, "Ali", 2, "Bobbi", 3, "Charli" );
local $, = " ";
print @arr, $/;

Using `$,` is just another way. But internally `$,` use `join` and is __not__ faster or more efficient as the `join` statement. Boris	[reply] [d/l] [select]
