Record locking 101

I had a program that was originally written in such a way that it would read/chain and lock a record while the user was in the maintenance screen. That would cause problems for a posting program that could also be run while records were being maintained. So I needed to eliminate the lock in the maintenance program. Thanks to this list, I modified the program so that the record data is now retrieved into a data structure temporarily (with supposedly no lock on the record) and then when the user presses enter the record is retrieved again from the DB, the data updated and written without delay so that the lock is very transitory.

Now comes time to test it. When this was originally reported as a problem, I looked at the code and found the flawed design and set about fixing it. I never looked at the job to see what the locks on the record actually looked like. So now I am viewing the record locks on the file and I am not sure what I *should* see. This is what I do see when I am in the record in the "view" mode (shouldn't be a lock on the record)

Record Lock Number Job User Number Status Type 494 QPADEV000R PETE 861530 HELD UPDATE

So I am guessing that I still have some more work to do, yes?
An UPDAT or DELET after a CHAIN would effectively release the lock on the record, correct?

What should the Lock Type be when you are just reading through the records with no need to update?

Thanks,

Pete
