[REBOL] Re: files out of order
From: ryanc:iesco-dms at: 29-Mar-2001 15:55
Use this before you pass the files to your read-directory-messages function:
sort-function: func [a b] [
a: info? a
b: info? b
a/date < b/date
]
sort/compare message-directory :sort-function
This function will only work if the files are referenced to the current working directory
(what-dir). Keep in mind the function passed to sort/compare can only take two arguments,
so use
inheritence to enhance it, such as with a path.
