CHAIN or READ without lock

Thought I would check if others have experience something like this.

The CHAIN or READ without lock is a new function (well sort of) , but do
you know it also READS LOCKED records.

We had duplicate invoice numbers in our order processing application.
It was caused by  the 'N'  (no lock ) on a CHAIN op.
I checked the manual and if you read the fine print, yes  you can read a
LOCKED record with
a CHAIN or READ  even if the file is opened for UPDATE, provided you use
a N to request a
read without lock.
Personally I stay away from the read without lock.
