Can a record be SELECTed twice in sort/selection processing?

[John Esak]

No, sorry, just using the DELETING metaphor to give you a ... well... a
metaphor.
 
I used to work for the comapny... I've seen the source code.  it can not
possibly select a record more than once.  That is, unless, as I stated you
are involving associated fields.

I'm not trying to do this, I just know that on at least two occasions a
record was processed twice and I found a situation where it just might have
been possible for the record to be selected twice.

I'm not sure that it works like "DELETING a record twice" since I think it
works more on the basis of building a table of records to run through during
output processing rather than flagging a record to be processed.

If it builds a table then it might be able to SELECT a record twice and have
the record placed in the table twice.  Ken probably knows if this is
possible or not.

No it is completely impossible. Think along the lines of DELETING a record
twice.  There is no meaning to it.  I think you might be trying to get at
associated field records or something... but they would each select
individually... and there is no real need to select a record more than once.
Just process those you think need that as many times as you would have
"selected" them. It pretty much would amount to the same thing.

"Can not" or "should not"?

(I'm reworking the program so as to avoid it, but I am now curious...If you
forced a sort/select program to walk through the records twice (say with a
lookup to whatever order it goes in to start from the beginning) and SELECT
the same record twice, will it show up twice to the output processing table.
(And, no, Ken, I didn't try it yet.:-)

No a record can not be selected twice in sort selection. Period. Don't even

try... :-)

If a sort/select program somehow sees and selects a record 

twice during 

it's processing, does that mean that the record will now 

appear twice to 

the output processing?



I think this happened in one of my programs, but I'm not sure 

if that's 

what I'm looking for or not.  An answer to this will help me 

nail down 

the source of the problem.



Thanks,



Boaz
