Manual Record Locking

If you are using manual record locking, use the READ statement to acquire a record lock.

To specify manual locking, use:

  1. The LOCK MODE IS MANUAL clause in the SELECT clause for the file
  2. The WITH LOCK clause on the READ statement

For example:

 select fd-name
     assign to "muser.dat"
     lock mode is manual
     read fd-name with lock
