I wonder if this would help?

By the way, I did post the LSELECT code to pickwiki, under UniQuerySource.

I'll have to play with this later - thanks for the info...

Since the index files are actually type 25 files, you can always (though of
course I would NEVER recommend this ... ) create a file pointer direct to
the INDEX.nnn and read the entries as records ... saves grabbing a select
list ..

Followed by a READLIST ...
Quite possibly - I can't remember.
One *important* point to note - if you are planning to call this from an
i-descriptor, as I did, don't forget you MUST save that to a non-default
list, or any attempt to LIST the idescriptor will go horribly wrong...
Cheers,

How would I get the contents of the Index?
George
Don't have the UV BASIC manual in front of me, but it's something like
READINDEX variable FROM filedescriptor, indexname[, indexvalue]
If you only pass filedescriptor and indexname, it will return a list of
all the index values. If you also pass indexvalue, it will return a list
of all keys for that value.
I'll have a look later and see if I can find that routine - it's
probably on my system somewhere, but my archives aren't that
organised...
Cheers,
Wol

Ok.
I have file1 - "people" that has @ID of PID I have file2 -
"registration" that has @ID of PID+EID+RID (EID = event id, RID =
registration id)
I want to select people who are not in the registration file with an
EID of "1".
With an SQL statement - I could join the two, then do the select or
use a subquery (I'm on UV 10.0.2 - not sure if sub querys work) Just
curious how this could be done with UV Native, and without involving a
program.
I first tried "SELECT REGISTRATION WITH EID = '1' SAVING UNIQUE PID"
-> "NSELECT PEOPLE"
But that returned 0 - since the NSELECT only works off the current
select list, not the whole file
Yes, I could create a temporary file, then select off that Yes, I
could read each people record, then loop through registration to see
if it doesn't exist.
Both of the above require programming I guess I could create a
subroutine that does the looping through registration, and put that
into an I descriptor - looking for another option.
Hmmm...
What I guess I'd do - create an index on file2 based on PID.
Create an idescriptor on file1 that gets the contents of that index. I
had a routine somewhere that got fed an index value and file, and
returned the contents of the index. It was quite useful, iirc.
Manipulate it from there. Probably selecting where there is no value
matching ...+1+...
Cheers,
Wol
