5.6 Using DECTPU Startup Files

5.6.7.2 Using an EVE Initialization File During an Editing Session

To execute an EVE initialization file during an editing session, use the @ (at sign) command and specify the file. For example, the following command executes an initialization file called MYEVE.EVE in your current (default) directory.

Command: @MYEVE

Commands for buffer settings apply to the current buffer. This is effectively the same as typing the commands that the file contains. You may want to create initialization files to execute two or more related commands, such as resetting both margins.

5.6.7.3 How an EVE Initialization File Affects Buffer Settings

Commands in an EVE initialization file that set buffer characteristics (such as margins and tab stops) affect a system buffer named $DEFAULTS$. Buffers created during the editing session have the same settings as $DEFAULTS$. For example, if your initialization file contains the command SET RIGHT MARGIN 65, the value 65 is used as the right margin setting for the main buffer and for any buffers you create during the session with GET FILE or BUFFER commands.

To see the settings for the $DEFAULTS$ buffer, use the EVE command SHOW DEFAULTS BUFFER. For example, if you want to know what the tab settings are for the $DEFAULTS$ buffer, type the following command:

Command: SHOW DEFAULTS BUFFER

This command causes EVE to show buffer information in a format similar to the format in Example 5–7 (using values that apply to your editing session).

To change the characteristics of the $DEFAULTS$ buffer during an editing session, use the command BUFFER $DEFAULTS$ to put the defaults buffer in a window. This buffer is empty and you cannot add text to it. However, when you change the settings of the $DEFAULTS$ buffer, the changes are saved and used to set the characteristics of any user buffers you create.

Use commands such as SET RIGHT MARGIN, SET LEFT MARGIN, SET TABS, FORWARD, REVERSE, INSERT, or OVERSTRIKE to change the characteristics of the $DEFAULTS$ buffer. The new characteristics are applied to new buffers but not to existing ones. To leave the $DEFAULTS$ buffer and put a different buffer in the window, use the BUFFER command.
