Re: Skip reading locked record to next record

["Mike Collins (syan)" <mike.collins@xxxxxxxxxx>]

And what if the record is locked by a user leaving their screen signed on? This
could loop for hours and hours, and kill your machine in the process! If the
file had a unique key what you could do is, read the file with NO lock, to
retrieve the key of the record ni question. Then chain to the file with this
key, and if the record is locked SETGT on the key, and go back to the initial
read with NO lock. Without a unique key this method would need some tweaking.
If order didn't matter you could use the same approach but use the RRN to
reposition.

Subject: Re: Skip reading locked record to next record

Dougl,
How about wrapping the Read in a DOW "Locked" loop

Like:
C                     READ RZUSSPV                3433

C           *IN33     DOWEQ*OFF
C                     MOVE 'LTL'     SPAPPL
C                     UPDATRZUSSPV
 * skip locked recs
C                     MOVE *ON       *IN34
C           *IN34     DOWEQ*ON
C                     READ RZUSSPV                3433
C                     ENDDO
*-----------
C                     ENDDO

C                     MOVE *ON       *INLR
