Hi Dave,

This sounded good, but OpenQM complains Sort item cannot be a literal

Sounds like a bug to me! This is the query processor trying to be too
clever. It rejects expressions that have no variable elements when used as
sort items. RND(), of

I'va made something like this on U2 too.
Juste make a derived field that use RND(@TIME) to generate a random
number. (maybe in a subroutine)
And use select like this :
SELECT MYFILE BY RANDOM_FIELD SAMPLE 100
But, as ordering record is made before sampling, it could take a little
time if you

This depends what you mean by random. If you are happy to agree that the
hashing process is effectively

Dave,
I'm wondering which would be more efficient; the basic subroutine or
Christophe's suggestion of an I descriptor?
Both solutions require that the entire file is read to construct the list.
There probably isn't a lot in it either way.

The I-desc is a nice idea, however you're going to get
multiple hits on the
same song, and don't we all hate that when we hear the same song?
The basic idea is very similar to something that I did with
