RE: SetLL And DESCEND

SETLL is not affected in anyway.  It will position to the value (or as
close as possible) the only difference using DESCEND is to read a higher
key value you READP instead of READ. 


Thanks,

Subject: Re: SetLL And DESCEND

I don't want the previous record, but let's just say that, in my
example, I know that the customer's record is greater than 95, but I
don't know exactly which value (it's a timestamp, and I only have the
date). By SETLLing to 96, with the values in this file, will I be
positioned to just before the 96 record?

BTW -- If the key wasn't descending, I know how it all works -- I am
just not sure how SETLL is affected by DESCEND.
