File locking was created by Mahesh
How to lock a file? Does 'jchmod +N' actually lock the file? Or is there any other way to lock a file and prevent updations to it until it is released?

Hi Mahesh,

jchmod +N will set only the NETWORK flag to TRUE.

To lock a file use FILELOCK command.

use F.READ - that will lock the record. when you use F.WRITE it will release the lock or if you use the RELEASE statement in your routine.

Yea, you are right in case of locking a record in a file. But the question here is to lock the entire file.
