4.2 Structuring Programs
Definition and applications
This TNC function enables you to comment part programs in
structuring blocks. Structuring blocks are short texts with up to 37
characters and are used as comments or headlines for the subsequent
program lines.
With the aid of appropriate structuring blocks, you can organize long
and complex programs in a clear and comprehensible manner.
This function is particularly convenient if you want to change the
program later. Structuring blocks can be inserted into the part program
at any point. They can also be displayed in a separate window, and
edited or added to, as desired.
The inserted structure items are managed by the TNC in a separate file
(extension: .SEC.DEP). This speeds navigation in the program
structure window.

corresponding NC blocks in the program window. This way you can
quickly skip large program sections.
