Re^2: combining two csv files by using math operations

I confirm this code works fine. This wisdom will be used in all derivatives of that code. I also see the advantages of using Data::Dump and noted #FIXME comments highlighting. Thank you very much! Any ideas how to trap an empty line at the end of a data file which it may have?

replace `my @multi_arrayA; push @multi_arrayA, [split(' ', $_)] for <dataA>;` [download] with: `my @multi_arrayA; push @multi_arrayA, [split(' ', $_)] for grep /\S/, +<dataA>;` [download] in both places, changing A to B in the second one, of course.	[reply] [d/l] [select]
