Re^4: Read Directory and getlines in .csv

Works beautifully. I think I need to look up a few things to see how/why/what of them like using "glob" and "unless. Whew! Most of the components you have in your code are what I had in mine. I was close, but, alas...no cigar. (sad face) BUT->I'm learning!! Thank you so much for your assistance. I kinda like Perl, its very powerful.

`glob` does more or less the same thing as opendir /readdir, except that it is more practical: first, it's one line instead or two, second it removes pseudo-directories such as "." and ".." which you usually don't want to explore, and finally it returns a list of files with their path, so that you can open them without having to add the path. `unless` does exactly what the English meaning of the word implies. It is essentially equivalent to `if not`. For example: `my $q = $c / $d unless $d == 0; # avoid division by zero error` [download]	[reply] [d/l] [select]
