d Editing a UNIT
Changes can be made either in the form or directly in the appropriate
conversational program block. Here you can decide yourself which
method you prefer.
If you want to modify the conversational program block concerned,
use the arrow keys to select the value to be corrected.
If you want to make changes via the form, proceed as follows:
 Select the initial block of the UNIT you want to edit
 Use the arrow key to move the cursor to the right: The TNC opens
the form
 Make the desired changes, save the changes with the END key and
quit the form.
If you wish to discard changes and you are still editing the
form, simply press the DEL key. The TNC then resets to
the data stored before you called the form.
Once you have inserted a UNIT for the first time, you can
insert any conversational program blocks in the UNIT. If
you insert conversational program blocks later and then
make changes via the form, then the TNC deletes the
inserted blocks again. In such cases you should always
make the changes via the conversational program editor.
It is not permitted to delete conversational program
blocks in the UNIT as it would lead to error messages and
incorrect machining.
