TPU

TPU: opens a TPU editor session.

Details

The TPU command enables you to use the OpenVMS TPU editor for editing instead of the default SAS text editor.

The command initiates a session of the TPU editor. When this session begins, the TPU window displays the contents of the window from which it was invoked, and the name of the window is displayed on the TPU status line. You can then edit the window's contents:

If you have WRITE access to the window (such as the Program Editor window), then you can save the changes that you make during the TPU session to the window when you exit from the editor, or you can save the changes to an external file.
If you have only READ access to the window, then a message on the message line of the TPU window alerts you to this fact. When you exit from the editor, you can save your changes to an external file, but you cannot save them to the window.

Special text attributes such as color or highlighting are lost during a TPU editing session. Therefore, when you issue the TPU command from a window that contains text with these attributes, a dialog box opens that enables you either to continue or quit the TPU command.

To suppress this warning, issue the HEATTR OFF command from the window's command line before you invoke TPU. Text attributes will then be deleted without warning. To redisplay the warning message, issue the HEATTR ON command from the window command line, and then issue the TPU command.

When you have finished editing in a TPU session, do one of the following:

To save the changes to the window, use the CTRL+Z key sequence or type EXIT at the TPU command prompt.
To discard the changes you made, type QUIT at the TPU command prompt.
To save the contents of the window to an external file, use the standard TPU commands. Then use the CTRL+Z command or the QUIT command, depending on whether you also want to save the changes to the window.

You can undo any changes you made to the window text during that session by issuing the UNDO command from the window command line.

Note: The SAS Session Manager, xsassm, must be running for the TPU command to work. [cautionend]
