Might be interesting to do a DSPRCDLCK on the file.
I'm guessing that each time you make a data change a new ODP is being
created, hence the SHRRD locks. (And it might be something to so with
the way SQuirreL is coded.)
I believe that you can have only one record at a time locked in a file.
If you ask SQL to do more than that, needed for cursor stability and
the like, I think it will put a *EXCLRD or *EXCL lock on the file.
Don't know if SQuirreL gives that capability.

I just went into one of our demonstration files using Squirrel SQL. I
then did a WRKOBJLCK on the file, from a terminal session, and found no
locks whatsoever on the file or the member, even though Squirrel was
displaying the entire file.
Then I right-clicked on the file in Squirrel, and selected "Make Editable."
At that point, a SHRRD lock appeared on the file. And when I made a data
change, another SHRRD lock appeared, with a third SHRRD lock appearing
when I changed something else.
At no time, though, did I see any record locks.
This is getting interesting: just how do record locks work in SQL?
