4.4 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
252 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. Use the
appropriate screen layout for this.
The inserted structure items are managed by the TNC in a separate
file (extension: .SEC.DEP). This speeds navigation in the program
structure window.
