Re: Problem when - use strict and -w

When I run your code without -w or use strict;, I get no complaints. However, when I run it with -w, I get your "uninitialized value" warnings, and I get the following warning:

Name "main::row" used only once: possible typo at ...

From this line of code:

      $row[0], "\"", " ", $row->[4],
      ^^^^

Did you see this warning too?

You should fix that error and continue to use strict and warnings.

Thank you both for your prompt reply. I had been staring at the code for a while but didn't see the typo in my code. Seemed that in the real code an empty last line of the data.txt also gave some problem. I'll find my way out of that (tomorrow, as it's too late here by now) And yes, I'll continue to use strict and warnings! Thanks again.	[reply]

As an aside, you could reduce the amount of typing by using qq in your print: `print "Olah:\t", $number++, qq(\t$row->[2] "$row->[5]"\t"$row->[3]$row->[0]" $row->[4]\n);` [download] I'm not sure if it's any prettier, but it is easier to type than all those commas and quotes and back-whacked quotes.
