CANCELING THE EFFECTS OF EDITING WORDS AND
BLOCKS
The effects of accidentally deleting and inserting words and blocks can
be canceled. This is called undoing.
Explanation
While a program is being edited in EDIT/MDI mode, the immediately
preceding editing operation, such as deletion or insertion, is stored.
Undoing refers to the function that cancels the effect of the
immediately preceding editing operation.
The following editing operations can be canceled by undoing.
- Deletion, overwriting, and insertion of words
- Cutting and pasting
Other operations (such as the replacement of words and the alteration
of program numbers) cannot be canceled.
Stored editing operation
The stored editing operation is erased upon any of the following
operations:
- Restoring a program to its previous state by undoing.
- Replacing a word or address in the program on which the editing
operation has been performed.
- Merging or copying the program on which the editing operation
has been performed.
- Registering or deleting the program on which the editing
operation has been performed.
- Changing the program number of the program on which the
editing operation has been performed.
- Condense the program memory (in EDIT mode only).
- Perform an operation or a reset (in MDI mode only).
Undoing
Procedure
(1) Select the program you want to restore to its previous state by
undoing.
(2) Place the program in the same editing status as that when the
editing operation was performed.
Example: To restore the program that was edited in the right
portion of the screen in MULTI EDIT mode
(simultaneous editing of two programs) in the
foreground, place the program in the right portion of
the screen in MULTI EDIT mode in the foreground.
(3) Press the [UNDO] soft key.
