Re: 'Invisible' newlines/line wrapping

Something in my code is inserting invisible newlines into my strings in a terminal, and I would like to have any suggestions as to how to fix my code to get rid of them, or where to find such info.

code causing newline (newline 'appears' directly after $index):
if($current!=1){
    say "$simple rad[$index] $current";
}
[download]

The much more plausible answer is that the value in $index ends with a newline. What's the output of

use Data::Dumper;
local $Data::Dumper::Useqq = 1;
print(Dumper($index));

`$index=<STDIN>;` [download] should be `chomp( $index=<STDIN> );` [download] You never removed the newline Enter produced.	[reply] [d/l] [select]
