Programming style guide
The programming guidelines described in the programming style guide help you to create a
uniform program code. You can better maintain and reuse the uniform program code. This
allows you to detect or avoid errors early on, for example, through compilers.
The programming style guide is available on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/109478084).
