Re^2: most efficient buffer sort

This is good stuff. However, having downloaded your CPAN module. Note that I changed the code above so it does a descending sort e.g.

for (rikeysort {/^\w+\s+(\d+)/; $2} <INPF>) {
[download]

This error now occurs

Can't call method "rikeysort" on an undefined value at ./x.pl line 401
+, <INPF> line 12.
[download]

There are only 12 records in my test input file
It works fine if I use ascending key sort
Any ideas what is happenning here ?

have you changed the `use Sort::Key` statement to import `rikeysort` instead of `ikeysort`? `use Sort::Key qw(rikeysort);` [download]	[reply] [d/l] [select]
