I'm guessing that the CHAIN statement is still erroring out, right? This is because you are not monitoring for an error condition on the CHAIN, causing the program to abort before it ever gets to your statement containing the %STATUS built-in.

Your easiest solution is to place the operation extender on the CHAIN statement:

Chain(e) k1 filename;

Alternatively, you could put the CHAIN statement inside a MONMSG block and check the status code inside the MONMSG block.  The operation extender is definitely the easier of the two solutions, however.

Bsidmis,

How did the adding the extender to your chain operation work?  Did it solve your problem?

Hi Tclukay,

Thanks for your Support

Yes the above opcode is Sucessful,But while Compiling the Physical file we have compiled with recodr wait time =60 ; So it takes 1 minute to display the error

So is there any alternative to reduce the time in displaying the Error

Regards,

Bsidmis

Well of course there's the most-obvious way of using the CHGPFM command from the command entry screen to change the wait time on the file you're using:

CHGPF FILE(myfile) WAITRCD(5)

The above command would change the wait time on a file named "myfile" from the default of 60 seconds to 5 seconds; you could actually set it to as low as zero seconds, but whatever you set it to, that would become the wait time for the file *regardless* of what application is using it.

If on the other hand you would like to just change the wait times for the file in this one RPG program, your best bet would be to place on OVRDBF command in a CL program, and have that CL program call the RPG program.  The OVRDBF command would look similar to the CHGPF command:

OVRDBF FILE(myfile) WAITRCD(5)

There are other ways of doing this, but these two would be the simplest.

Oops, one quick correction...

If you want a "zero wait time" on record locks, I believe the WAITRCD parameter would be WAITRCD(*immed), not WAITRCD(0)... sorry for the confusion.
