Probs simple but need help - Perl

Mr. P-teo

hy everyone, i need some help with something i belive would be very simple. I need to make an if statement that basically says,
if $input = nothing then print enter text else print $input.

I tried the following but doesn't work. Can anyone help?


if ($input eq NULL){
    print \"\nPlease enter text&#46;&#46;&#46;\";
} else {
     print \"$input&#46;&#46;&#46;\n\n\n\";
}

#!C&#58;\Perl64\bin\perl&#46;exe
print \"enter text\";
chomp($input = &lt;&gt;);
if($input eq '')
{
	print \"enter something!\n\n\";
} else {
	print \"bleh\n\n\";
}

Here's a better version:

#!C&#58;\Perl64\bin\perl&#46;exe
while(1)
{
	print \"Enter text&#58; \";
	chomp($input = &lt;&gt;);
	if($input eq '')
	{
		print \"Enter something!\n\n\";
	} else {
		print \"You entered $input\n\n\";
		exit;
	}
}

I don't program in perl, but in other languages it isnt


if value = null

it is


if value is null

Or the equivelent in perl.

Howdy, Stranger!
