Getting Started with DECTPU

2.3 Invoking DECTPU from a Batch Job

2.3 Invoking DECTPU from a Batch Job

If you want your edits to be made in batch rather than at the terminal, you can use the DCL command SUBMIT to send your job to a batch queue.

For example, if you want to use the file GSR.TPU (shown in Example 2–4) to make edits in batch mode to a file called MY_FILE.TXT, enter the following command:

$ SUBMIT invisible_tpu.COM/LOG=invisible_tpu.LOG/parameter=my_file.txt

This job is then entered in the default batch queue for your system. The results are sent to the log file that the batch job creates.

In batch DECTPU, EXIT is the same as QUIT.

2.4 Using Journal Files

Journal files help you to recover your work when the system fails. This section discusses the journaling methods you can use with DECTPU.

DECTPU offers two journaling methods:

•Keystroke journaling

•Buffer-change journaling

You can use both keystroke and buffer-change journaling at the same time (except on DECwindows, where you can use only buffer-change journaling). To turn on keystroke journaling, the application uses the JOURNAL_OPEN built-in.

The application layered on DECTPU, not the DECTPU engine, determines what kind of journaling is turned on and under what conditions. Table 2–2 shows the journaling behavior established by EVE.

Caution

Journal files contain a record of all information being edited. Therefore, when editing files that contain secure or confidential data, be sure to keep the journal files secure as well.

You must use the same major version of DECTPU to recover the journal that you used to create it.
