Editing program lines
While you are creating or editing a part program, you can select any
desired line in the program or individual words in a block with the
arrow keys (see table at right). While you are entering a new block
the TNC identifies the block with a * as long as the block has not
been saved.

Looking for the same words in different blocks

To select a word in a block, press the arrow keys
repeatedly until the highlight is on the desired
word.

Select a block with the arrow keys.

The word that is highlighted in the new block is the same as the
one you selected previously.

Finding any text

To select the search function, press the FIND soft key.
The TNC displays the dialog prompt FIND TEXT:

Enter the text that you wish to find.

To find the text, press the EXECUTE soft key.

Inserting blocks at any desired location

Select the block after which you want to insert a new block and
initiate the dialog.

Inserting the previously edited (deleted) block at any desired
location

Editing and inserting words

Select a word in a block and overwrite it with the new one. The
plain-language dialog is available while the word is highlighted.

To save your changes, press the END key.

To reject the change, press the DEL key.

If you want to insert a word, press the horizontal arrow key
repeatedly until the desired dialog appears. You can then enter the
desired value.

Block display

example in a fixed cycle), this will be indicated with ”>>” at the
right edge of the screen.
