Structuring programs

Definition and applications

The control offers you the possibility to comment part programs
in structuring blocks. Structuring blocks are 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.
Structure blocks can also be displayed in a separate window, and
be edited or added to, as desired. Use the appropriate screen
layout for this.
The control manages the inserted structure items in a separate
file (extension: .SEC.DEP). This speeds navigation in the program
structure window.
The PROGRAM + SECTS screen layout can be selected in the
following operating modes:
Program run, single block
Program run, full sequence
