Simple Numeric Sort

Wrong: 

foreach $item (sort(keys(%Dictionary)))

Right: 

foreach $item (sort { $a <=> $b } keys (%Dictionary))

The first example does a string sort, so in this case you can end up with sequences which look like

  • 1 2 3 44 5
The second example returns the correct order.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
