Re^2: How to add a new column into my csv file?

Hi,

Thanks for the suggestion but may I know what's the reason behind it? Is split not efficient? Sorry, I just started to learn Perl few weeks ago.

what's the reason behind it? The modules will handle any complications: embedded separation characters, quoting rules, missing columns, character encoding, EOL issues, etc. split will simply split a string into a list which is fine for trivial, well-formed in-memory CSV datasets. To go beyond such datasets would be tortuous without using Text::CSV_XS et al. It is the same reason why you would not be recommended to use regular expressions to parse any but the most trivial XML sets, for example. Update: (edited for typo)	[reply]
