Hi,
First, thanks again for all who helped me with sorting dates with Date::Manip. That's working great.
I have another question. Below is a "sample" of a larger script. I have it working great, but I'm pretty sure the sorting and manipulation of file data is inefficient. What I'm asking is, how do I make the code more efficient? Here's the code and what it does.
If I get a chance, I'll try to look more closely at your code. But I do want to mention these two references for understanding some of the theory of sorting in Perl:
Uri Guttman and Larry Rosler, "A Fresh Look at Efficient Perl Sorting." http://www.sysarch.com/perl/sort_paper.html
and
David Cross, "Data Munging with Perl," Manning, 2001, pp 40-47.
