Controlling Windows

The following commands are used to control windows. (Remember DO before and RETURN after):

SPLIT WINDOW

Splits the current window screen into two:

• The current buffer is displayed in both windows.
• They can be scrolled independently.
• Changes in one window will occur in the other because the same buffer is being displayed.

SHRINK and ENLARGE

Change the size of the current window.

SHRINK number

ENLARGE number

These makes the window smaller or larger by number lines.

OTHER

Move the cursor to the next window. The window that holds the cursor is the current window.

WINDOW

Closes the current window. The buffer is still present. It can be displayed by using the SHOW BUFFER command and selecting that buffer (see below).

ONE

Return the display to one window. The current window is retained.

GET

Load another file into the current window:

• This creates another buffer.
• It can be used when only one window is displayed.
• See the OPEN and OPEN SELECTED commands in HELP.

QUIT, EXIT and WRITE

The QUIT and EXIT commands take account of multiple buffers:

• They are always applied to the current buffer.
• When appropriate, you are asked about other buffers.

The WRITE command saves only the current buffer without leaving EVE.

SHOW BUFFER

This command is used to change the buffer displayed in the current window. To use it:

1. Press DO
2. Enter SHOW BUFF
3. Move the cursor to the required buffer.
4. Press the SELECT key

When a buffer's name is known, it can be immediately displayed using:

1. Press DO
2. Enter BUFFER buffername
3. Press RETURN

SHOW

This command gives detailed information about all the data buffers. Information includes input and output file names, width, margins and marks.

DELETE BUFFER

This command closes the current buffer:

• If it has been changed, you are asked if you want to write its contents to a file.

• When a buffer is open it uses computer memory, so when you are editing or referencing a large number of files:

Delete buffers when they are no longer needed. Most EVE users do not need this command because they never edit more than one or two files at the same time.
