MOVE LEFT
The MOVE LEFT command moves the cursor left one character or column at a time. If the cursor is free (the default setting), you can move it anywhere in the buffer, whether characters are already there or not. For example, if the left margin is greater than 1, you can move left of the left margin. If the window is shifted to the right, you cannot move the cursor past the left edge of the window.If the cursor is bound, then from the start of a line it moves to the end of the previous line, if there is one. When you edit an EVE command line, the cursor is always bound and does not move past the start of the line.

MOVE RIGHT
The MOVE RIGHT command moves the cursor right one character or column at a time. If the cursor is free (the default setting), you can move it anywhere on the screen, whether characters are already there or not. For example, you can move right of the right margin. You cannot move the cursor past the right edge of the window.If the cursor is bound, then from the end of a line it moves to the start of the next line, if there is one. When you edit an EVE command line, the cursor is always bound and does not move past the end of the line.
| EVE Default: | <uparrow symbol> |
| VT100 Keypad: |

MOVE UP
The MOVE UP command moves the cursor up a line at a time. If the cursor is free (the default setting), it moves up in the same column on the screen, regardless of whether text is there or not.If the cursor is bound, it moves up to the corresponding line position, as in EDT, WPS, and other editors. For example, from the end of a line longer than the previous line, MOVE UP moves the cursor to the end of the previous line. It does not move into the unused portion of the buffer.
NEW
The NEW command creates a new buffer, putting it into the current EVE window. The cursor moves to the top of the new buffer. NEW tries to create a buffer named MAIN. If a buffer named MAIN already exists, EVE asks you for the name of the new buffer to create. Pressing the Return key or the Do key at the prompt without typing anything cancels the operation.You cannot create a buffer with the same name as an existing buffer. For example, you cannot create a buffer named MESSAGES because EVE has a system buffer with that name (for storing the messages you receive during your editing session). For a list of the buffers you have created, use the SHOW BUFFERS command. For a list of the buffers created by EVE, use the SHOW SYSTEM BUFFERS command.
Buffers you create have the same margins and other settings as an EVE system buffer named $DEFAULTS$.
The following command creates a new buffer. Since a buffer named MAIN already exists, EVE asks you for a buffer name. When you enter test, EVE creates a buffer named TEST.
Command: NEW
Type a new buffer name or press RETURN to cancel: TEST
|
NEXT BUFFER
The NEXT BUFFER command puts your next buffer into the current EVE window if you have two or more buffers, and returns the cursor to your last position in that buffer. With NEXT BUFFER, you can toggle between two buffers or cycle through several buffers without having to type their names. It does not create a new buffer or re-create a deleted buffer.If you have more than two buffers, the next buffer is determined by the order in which you created the buffers. Conceptually, the list of buffers is circular so that repeating NEXT BUFFER cycles through your buffers. For a list of your buffers, use the SHOW BUFFERS command.
NEXT SCREEN
| EVE Default: | NEXT SCREEN |
| VT100 Keypad: | KP0 |
The NEXT SCREEN command scrolls text vertically to show the next screen's text---roughly, the length of the current EVE window. If the cursor is free (the default setting), it moves down in the same column on the screen, regardless of whether text is there or not. Conceptually, the cursor remains in the same position on the screen while the buffer scrolls down.If the cursor is bound, it moves down by the corresponding line positions, depending on the shape of your text.
You can also press Next Screen to scroll through a lengthy help topic.
The EDT keypad redefines the Next Screen key to scroll down 75% of the window size.
| EVE Default: | GOLD-Next Screen |
NEXT WINDOW
The NEXT WINDOW command puts the cursor at your last position in the next window, if you are using two or more windows in EVE (same as the OTHER WINDOW command). If you are using only two windows, the NEXT WINDOW, OTHER WINDOW, and PREVIOUS WINDOW commands are the same. If you are using three or more windows, NEXT WINDOW lets you cycle through your windows as follows:
- From the top window, the cursor returns to your last position in the middle window.
- From the middle window, the cursor returns to your last position in the bottom window.
- From the bottom window, the cursor returns to your last position in the top window.
For more information about using multiple windows in EVE, read the online help topic on Windows.
If the $CHOICES$ buffer is displayed, such as when you type an ambiguous command, you can press a key defined as NEXT WINDOW to move between the $CHOICES$ buffer and the command line.
Note
The GOLD-Next Screen is a "sleeper" key, meaning that EVE defines this key sequence but does not define a default GOLD key. The definition is enabled when you use the SET GOLD KEY, SET KEYPAD EDT, or SET KEYPAD WPS command, unless you have otherwise defined it yourself.
ONE WINDOW
The ONE WINDOW command restores a single, large window when the EVE main window is split into two or more windows. If you are not in the window you want to keep, use the NEXT WINDOW, OTHER WINDOW, or PREVIOUS WINDOW command. EVE deletes all the windows except the current window. The buffers associated with those windows are not deleted.For more information about using multiple windows in EVE, read the online help topic on Windows.
OPEN input_filespec
input_filespec
The file you want to edit or create. You can use logical names and you can use wildcards in the file specification. If more than one file matches your request, EVE shows a list of the matching files so you can choose the one you want. You can edit several files in an editing session, but you can specify only one file at a time. If you do not specify a file, EVE prompts for one. Pressing the Return key or the Do key at the prompt without typing anything cancels the operation.
The OPEN command puts the file you specify into the current EVE window, creating a new buffer if necessary. You can edit another file in the same session. This command is the same as the GET FILE command. If you specify an existing file, EVE copies it into a new buffer in the current window. If the file does not exist, EVE creates a new empty buffer that uses the file name and file type as the buffer name.If you specify a file that you have already read into the editing session---that is, a file for which there is already a buffer---EVE returns to your last location in the buffer for that file, if the buffer still exists.
If you use a search list or wildcard directory (such as [...]) to specify a file, EVE gets the first matching file found---without displaying the $CHOICES$ buffer.
New buffers have the same margins and other settings as an EVE system buffer named $DEFAULTS$.
OPEN SELECTED
The OPEN SELECTED command opens the file whose name you have selected or found. This is the same as using the GET FILE or OPEN command without having to type the file name. OPEN SELECTED is useful to open a file that has a long name, or a name similar to other files, without having to type it exactly.For more information, see the description of the GET FILE command.
| EVE Default: | GOLD-Next Screen |
OTHER WINDOW
The OTHER WINDOW command puts the cursor at your last position in the next window, if you are using two or more windows in EVE. This command is the same as the NEXT WINDOW command. If you are using only two windows, the NEXT WINDOW, OTHER WINDOW, and PREVIOUS WINDOW commands are the same. If you are using three or more windows, use the NEXT WINDOW command.For more information about using multiple windows in EVE, read the online help topic on Windows.
If the $CHOICES$ buffer is displayed, such as when you type an ambiguous command, you can press a key defined as OTHER WINDOW to move between the $CHOICES$ buffer and the command line.
Note
The GOLD-Next Screen is a "sleeper" key, meaning that EVE defines this key sequence but does not define a default GOLD key. The definition is enabled when you use the SET GOLD KEY, SET KEYPAD EDT, or SET KEYPAD WPS command, unless you have otherwise defined it yourself.
OVERSTRIKE MODE
The OVERSTRIKE MODE command sets the mode of the current buffer to overstrike, as opposed to insert. In overstrike mode, each character you type replaces the character at the current position. (In some editors, this is called typeover mode or replace mode.)The mode of the current buffer is shown in the status line. You can have one buffer set to insert and another buffer set to overstrike. For buffers you create, the default is insert mode.
The default mode for editing EVE command lines or prompt lines matches your terminal setting (on character-cell terminals only), according to the DCL command SET TERMINAL, independent of the mode of your text buffers.
If you use SET BOX NOPAD, the mode of the buffer determines the effects of BOX CUT and BOX PASTE. In overstrike mode, BOX CUT pads the area with spaces where you cut the text. To override these effects, use BOX CUT INSERT and BOX PASTE INSERT.
For a list of the commands and keys affected by the mode of the buffer, see Table 2-3.
| WPS Keypad: | GOLD-PF2 |
PAGINATE
The PAGINATE command inserts a "soft" page break for a 54-line page, erasing any existing soft breaks within the 54 lines. A soft page break is a form feed followed by the null character and appears as a small FF NL .If a "hard" page break is found, EVE stops on the line after that page break, in case you want to erase it. A hard page break is a form feed only and appears as a small FF . Usually it is inserted with the INSERT PAGE BREAK command (Ctrl/L or with the WPS keypad, GOLD-N).
| EVE Default: | PASTE |
| VT100 Keypad: | KP9 |
| EDT Keypad: | GOLD-KP6 |
PASTE
The PASTE command inserts the text you have copied or removed. This command is the same as the INSERT HERE command.By default, the text is inserted whether the buffer is in insert or overstrike mode. Existing text is pushed to the right or down. Depending on the amount of text inserted and where you are on the line, your text may go past the right margin or even partly out of view. Use FILL commands, if necessary, to reformat (rewrap) your text.
If SET BOX SELECT is in effect, PASTE is the same as BOX PASTE, usually overwriting existing text. See the description of the BOX PASTE command or read the online help topic on Ranges and Boxes.
Depending on your setting, the text is inserted either from the PASTE buffer in EVE or from the DECwindows clipboard. The default is SET NOCLIPBOARD, which uses the PASTE buffer. For more information, see the description of the SET CLIPBOARD command.
The PASTE command is not the same as the WPS keypad Paste key. The PASTE (or INSERT HERE) command uses either the INSERT HERE buffer in EVE or the DECwindows clipboard, depending on your setting. The WPS Paste key uses either the INSERT HERE buffer or a WPS-style alternate paste buffer but does not use the clipboard.
PREVIOUS BUFFER
The PREVIOUS BUFFER command puts your previous buffer into the current EVE window if you have two or more buffers. With PREVIOUS BUFFER, you can toggle between two buffers or cycle through several buffers without having to type their names. (It does not create a new buffer or re-create a deleted buffer.)If you have more than two buffers, the previous buffer is determined by the order in which you created the buffers. Conceptually, the list of buffers is circular, so that repeating PREVIOUS BUFFER cycles through your buffers. For a list of your buffers, use the SHOW BUFFERS command.
| EVE Default: | PREV SCREEN |
| VT100 Keypad: | PERIOD |
PREVIOUS SCREEN
The PREVIOUS SCREEN command scrolls text vertically to show the previous screen's worth of text---roughly, the length of the current EVE window. If the cursor is free (the default setting), it moves up in the same column on the screen, regardless of whether text is there or not. Conceptually, the cursor remains in the same position on the screen while the buffer scrolls up.If the cursor is bound, it moves up by the corresponding line positions, depending on the shape of your text.
You can also press Prev Screen to scroll through a lengthy help topic.
The EDT keypad redefines the Prev Screen key to scroll back 75% of the window size.
| EVE Default: | GOLD-Prev Screen |
PREVIOUS WINDOW
The PREVIOUS WINDOW command puts the cursor at your last position in the previous window, if you are using two or more windows in EVE. If you are using only two windows, the PREVIOUS WINDOW, NEXT WINDOW, and OTHER WINDOW commands are the same. If you are using three or more windows, PREVIOUS WINDOW lets you "cycle" through your windows as follows:
- From the bottom window, the cursor returns to your last position in the middle window.
- From the middle window, the cursor returns to your last position in the top window.
- From the top window, the cursor returns to your last position in the bottom window.
For more information about using multiple windows in EVE, read the online help topic called Windows.
If the $CHOICES$ buffer is displayed, such as when you type an ambiguous command, you can press a key defined as PREVIOUS WINDOW to move between the $CHOICES$ buffer and the command line.
Note
GOLD-Prev Screen is a "sleeper" key, meaning that EVE defines this key sequence but does not define a default GOLD key. The definition is enabled when you use the SET GOLD KEY, SET KEYPAD EDT, or SET KEYPAD WPS command, unless you have otherwise defined it yourself.
| WPS Keypad: | GOLD-K |
QUIT
The QUIT command ends the editing session without writing out a new file or new version of an existing file. Quitting discards the edits made during the session---except those you have already saved by using SAVE FILE or WRITE FILE commands.If you have modified any buffers that you created, EVE asks you to confirm that you want to quit (to prevent accidentally discarding your edits). If you want to quit, type YES and press the Return key. If you do not want to quit, type NO and press Return.
If you did not modify any buffers, or if you have already saved all your edits, then the EXIT and QUIT commands are the same. Thus, you can quit by pressing a key defined as EXIT, such as F10 or Ctrl/Z.
If you have changed attributes and not saved them, then when quitting, EVE prompts you as follows:
Command: SET CURSOR BOUND Command: SET FIND CASE EXACT Command: SET TABS VISIBLE . . . Command: QUIT Attributes were changed. Save them? [YES]If you want to save the changes, press the Return key. EVE then does a SAVE ATTRIBUTES command before quitting. If you do not want to save the changes, type NO and press Return. EVE then continues quitting.
To disable this prompting (to make exiting faster or simpler) use the SET NOEXIT ATTRIBUTE CHECK command. However, the setting does not apply to the current editing session but only to subsequent editing sessions that use the section file or command file in which you save the setting.
