RE: Blocked records

[Buck Calabro <mcalabro@xxxxxxxxxxxx>]

Raul,
You can easily change the wait time for locked records with OVRDBF filename
WAITRCD(1).
You can add program handling of this error by putting an indicator in the LO
positions (I/O error) of your CHAIN or READ statement.  If that indicator
comes on, you have some sort of I/O error.  You can check the file's *STATUS
to see what exactly what error you got:
FLOCK    UF  E           K        DISK                   
F                                              KINFDS INFDS   
IINFDS       DS                                               
I                                     *STATUS  FSTAT          
I           SDS                                               
I                                     *STATUS  PSTAT
I                                       91 170 PSMSG          
C           KEY       CHAINLOCKR                8030          

80 = No record found (HI)
30 = I/O error (LO)

When this gets a record lock, 
FSTAT = 01218
PSTAT = 0
PSMSG = RECORD 1 IN USE BY JOB 711466/BUCK/BUCK01.

RPG IV is similar, but you don't need the indicators if you don't like them.
You can use the %found and %errror instead.
