EDIT
MODE
EDIT
Selects the Edit mode for editing programs in the control memory.
INSERT
Inserts the text in the input buffer after the current cursor location. Also used to copy blocks of code in a
Program.
ALTER
Changes the item that the cursor is on to the text in the input buffer. Places an MDI program in the program
list.
DELETE
Deletes the item that the cursor is on.
UNDO
Backs out or undoes up to the last 9 simple edit changes.
A very powerful keyboard button available in this control is the UNDO button. When editing, this button will
allow you to basically undo any changes or edits you have made but wish you had not. Any time you use the
INSERT, ALTER, or DELETE buttons, the condition of the original block is saved and can be restored with the
UNDO button. In fact, the previous nine changes can be undone in the opposite order that they were entered by
pressing the UNDO button for each change that is to be backed out. Sometimes you can even make some
simple edits with INSERT, ALTER, and DELETE, then cycle through a program, and if you didn’t like the edit’s
that were done, go back into EDIT and press UNDO. Sometimes it will undo it for you, and sometimes it won’t.
If it doesn’t, then you’ll get the message “Can’t UNO!”
The UNDO button can be used in EDIT, BACKGROUND EDIT, and MDI. However, if you change operating
modes between EDIT and MDI, you cannot use the UNDO button because the list of saved data is cleared.
You cannot UNDO anything done in BLOCK EDIT. The only thing UNDO does for you with a BLOCK EDIT is it
will undo a highlighted block selection and go back to a simple cursor.
