Sort with more than three keys

[Russell May]

I have need to sort text on five keys. Now I can use Supersort (16-bit MSDOS program) in Windows 7 64-bit XP Mode; or use Textpad by rearranging columns, sorting, and then disarranging columns. Both methods are inconvenient.

Edit: I found a solution using CMsort, which is a 32-bit command-line sort program. It is similar in some ways to SuperSort but more limited and verbose, and less forgiving of the text file format.
