When you submit a batch job, the output to be written to the log file
is stored in an output buffer. Periodically, the buffer is flushed and
its contents are written to the batch job log file. By default, the
buffer is flushed once a minute; therefore, you can type the log file
to determine how much of the job has completed while the job is still
To change the default output rate, include the SET OUTPUT_RATE command
in the command procedure that you are submitting as a batch job. When
the SET OUTPUT_RATE command is executed within a batch job and a delta
time is specified, DCL flushes the buffer, sets the default output
rate, and starts a new output interval.
If the SET OUTPUT_RATE command is executed within a batch job and a
delta time is not specified, DCL flushes the buffer but does not change
the default output rate and does not start a new interval.
If you issue the SET OUTPUT_RATE command interactively, or within a
command procedure that is executed interactively, then no action is
