Numbering the program blocks
Note
The buffer memory contents are retained even after the editor is closed, enabling you to paste
the contents in another program.
Note
Copy/cut current line
To copy and cut the current line where the cursor is positioned, it is not necessary to mark or
select it. You have the option of making the "Cut" softkey only operable for marked program
sections via editor settings.

Press the "Cut" softkey to delete the selected program blocks and to copy
them into the buffer memory.
Note: When editing a program, you cannot copy or cut more than 1024
lines. While a program that is not on the NC is opened (progress display
less than 100%), you cannot copy or cut more than 10 lines or insert more
than 1024 characters.
If you have selected the "Automatic numbering" option for the editor, then
the newly added program blocks are allocated a block number (N num‐
ber).
The following rules apply:
● When creating a new program, the first line is allocated the "first block
number".
● If, up until now, the program had no N number, then the program block
inserted is allocated the starting block number defined in the "First
block number" input field.
● If N numbers already exist before and after the insertion point of a new
program block, then the N number before the insertion point is
incremented by 1.
● If there are no N numbers before or after the insertion point, then the
maximum N number in the program is increased by the "increment"
defined in the settings.
Note:
After exiting the program, you have the option of renumbering the pro‐
gram blocks.
