He was saying that he created a second logical to read from that is INPUT
only, so that when the record is read it won't be locked.  That's the only
reason he created the second logical.  So our suggestions were for him to
not deal with the second logical and just use the extender (N) on the first
logical to load the subfile so that the records are not locked when read.
Creating the new logical allowed him to have two logicals in the program,
one for input and the other for update.

I guess I might be misunderstood the problem.  The original email
indicated that he created a new logic with same key to avoid record
lock.  If the problem Ken is encountering is what your are describing,
how would creating a new logic correct the problem?

Lim, if you are reading an update-able file to load the subfile, the
last record read will be locked unless you use the (N) extender.  That
record will remain locked until UNLOCK?, UPDATE, DELETE, or another read
is performed.


The issue that this causes is when a second person calls the program up.
The second person will not be able to load their subfile because the
READ is trying to gain an exclusive lock on a record that is already
locked.
It's my opinion that you should always load subfiles with the (N)
extender.

As long as the loading and updating is done in the same program on the
same file, you should not get record lock problem.  Are you actually
having record lock problem?

Subject: reads and updates on the same file

This program displays a subfile of all records in the file and  later
updates individual records.
To avoid record locks, I created a new logical file with the same key as
the originals.
Is there a more elegant solution, which avoids creating a second
logical?
This is my first posting, so I would appreciate any advice.
Thanks, Ken
