4.2 Structuring Programs
To keep track of long programs you can enter
structuring blocks as texts in the TNC program. The
TNC then displays these structuring blocks in the
right screen window. To page through the program
you can:
• Scroll up and down in the program NC block by
NC block in the left screen window
• Scroll up and down in the program structuring
block by structuring block in the right window
If you are scrolling through the program block by
block in the right screen window, the TNC at the
same time automatically moves the corresponding
NC blocks in the left window. This way you can
skip any desired number of NC blocks by simply
pressing a key. With the aid of the CHANGE
WINDOW soft key, you can switch from the left to
the right window, and vice versa. The background
color of the screen window can be selected
through machine parameters.
The CHANGE LEVEL soft key determines for which
of the two available levels a structuring block is
defined. The second level is indented in the screen
window (see Fig. 4.3).
You can edit existing structuring texts and the level
of a structuring block for both windows by moving
the highlight with the horizontal cursor keys to the
block to be changed.

Inserting a structuring block in the left screen window
You initiate the dialog for structuring block entry by pressing the INSERT
SECTION soft key. The structuring block is inserted behind the current
block.
STRUCTURING TEXT ?
Enter the structuring text with the ASCII keyboard (244 characters maximum).
If necessary, change the level of the structuring block. You can choose
from two levels.
Inserting a structuring block in the right screen window
Simply enter the text with the ASCII keyboard; the TNC automatically
inserts the new structuring block behind the active structuring block.
The most convenient way to structure programs is to switch the screen layout to PGM+SECTION (see page 1-6).
