This display may be retrieved after inserting lines by pressing ENTER.
To return from insert mode to edit mode, press the EDIT soft key.
DELETE: allows the line currently displayed to be deleted.
↓ and ↑ : allow the user to step through the program in either direction, a line at a time.
Alternatively, if the key is held pressed, an auto repeat feature keeps
presenting new lines until the key is released.
QUIT: is pressed to indicate that editing is complete.
The final entry in a correctly terminated program is always '99*Q'.
12.3.6 EDITING A PROGRAM: FROM AN EXTERNAL DEVICE
a. To enter Edit Mode for program number 'n', send the command *En from the
external device. The message: EDIT MODE, and the first program line are sent by
the 1250 to the device (e.g. printer).
b. To step to the next line of the program, send the command *F. To step backwards to
the previous line, send *B.
c. The current line may be deleted using the *D command.
d. To insert a line or lines before the current line, enter Insert mode, by sending the
command *I, and then input the required line(S).
e. To exit from any of the modes, send the command *Q.
After this command it is necessary to re-enter Edit Mode to perform further edits. The
full list of Edit commands available is given in chapter 13, at the end of section 7.20.
12.3.7 COPYING A PROGRAM
The following example shows how to copy a program to a free program number.
Note: programs can only he copied into the non volatile memory when the keyswitch is
in the 'supervisor' position. Also see Note in Chapter 12 section 3.4.
1. Press the PROGRAM LEARN hardkey. The display will show:
PROGRAM
LEARN EDIT CLEAR COPY
2. Press the Copy softkey. The display will now show:
COPY FROM PROGRAM ()
LEARN EDIT CLEAR COPY
3. Enter the number of the program to be copied, for example number 2. The display
will now show:
COPY FROM PROGRAM 2 TO PROGRAM ( )
LEARN EDIT CLEAR COPY
4. Enter the number of the program that is to receive the copy. This number must be
different to the number of the 'program to be copied' entered in step 3, and must not
already exist before the copy is executed. If this number does already exist, the
existing program must be cleared before any other program can be copied to it.
The display should now take on the form:
100.00Hz + 3.45 V j -1.05V
[TIME 00:42:35] COPYING
5. When the copy is complete the display will show:
100.00Hz + 3.45 V j -1.05
[TIME 00:42:35] COPY COMPLETE
