( #3333=superdoc: print w/ replies, xml ) Need Help??

The sorting on 4 columns of a 40 column textfile with the Schwartzian Transform works fine, except the date column.

It's in DD-MM-YYYY format and alfabetically/numerically handled as a string.

Do I have to convert this column before the ST to a number, sort it during the ST as a number, and after the ST convert it back to the DD-MM-YYYY format?

Or is there an elegant solution within the ST possible?

I think, the first option will harm the performance...

Any expert advice is very welcome.

Thanks.
