Re^2: No output to screen or output file

Dont I have to format my code with those single quotations when comparing string values? For that reason, I have the program check and differentiate between strings and numerical values (string or num) - I posted a question earlier and the solution to my problem was to include these single quotations. I believe I kept getting an error when trying to run the program without them.

Here's the quick explanation. What does this piece of code mean? `my $result = something;` Is `something` a function call? Is it a string literal? You have to make your intent clear to Perl and to human readers. Make it unambiguously a function call with: `my $result = something();` ... or a string with: `my $result = 'something';` Where it's not obvious what you mean, make it obvious. That's what strict was complaining about. Improve your skills with Modern Perl: the free book.	[reply] [d/l] [select]
