2-7. MPE/3000 and EDIT/3000 SPECIAL CONTROLS
In an interactive session, the following MPE/3000 special controls allow
you to correct typing errors, temporar- ily suspend EDIT/3000 operation,
and type continuation lines.
CONTROL X To delete a line that you have typed in from the
terminal (and before you press the RETURN key), type
CONTROL X or the equivalent (press and hold CONTROL or
its equivalent and press X). MPE/3000 prints !!! and
returns the carriage or cursor. Now you can type the
corrected line.
For example,
|----- CONTROL X entered here
v
:EDIKOR!!!
EDITOR
CONTROL H To erase the last character typed, type CONTROL H or its
equivalent (press and hold CONTROL or its equivalent and
press H). MPE/3000 prints an indication of the erasure
(such as a back slash, or a backspace and a back slash,
depending on the terminal type). It is now possible to
type the correct character. To erase more than one
character, type CONTROL H once for each character to be
erased.
An example of CONTROL H is as follows:
|---- CONTROL H entered here
v
:FILE OUT;SAW\VE
The corrected line is entered into the computer as:
:FILE OUT;SAVE
BREAK To suspend EDIT/3000 operation temporarily, press the
BREAK key or its equivalent. Control is passed to
MPE/3000, which prints a colon prompt character and
waits for a command. When you are ready to resume
EDIT/3000 operation, type :RESUME. MPE/3000 prints the
message READ PEND- ING. Now, enter data or commands to
resume EDIT/3000 operation.
An example appears in Figure 2.3. Here, the user has
suspended EDIT/3000 operation to display files to which
he may have access by entering the :LISTF command.
See also the : command, described in Section III, which
allows you to enter certain system com- mands from
within EDIT/3000.
LINE FEED To continue any input line to the next line, press LINE
FEED or its equivalent. MPE/3000 will space one line
and you can continue to type. (Note: This is most
useful when editing text lines which exceed terminal
line length.)

Figure 2.3. Using the BREAK Key
If the terminal being used is a device not normally furnished by
Hewlett-Packard, the keys used for CONTROL X, CONTROL H, BREAK, and LINE
FEED may have other labels. See the MPE Commands Reference Manual for
terminal characteristics.
In addition to the MPE special controls described above, CONTROL Y is a
special control provided by EDIT/3000. It can be used during EDIT/3000
operation only and is useful solely in interactive sessions.
CONTROL Y To terminate EDIT/3000 command execution during an
interactive session on HP terminals, press CONTROL Y
(hold control key and press Y) or its equivalent.
EDIT/3000 displays...and a slash to prompt for the next
command.
An example of CONTROL Y usage is shown in Figure 2.4.
