Creating a program block

In order to structure programs to achieve a higher degree of transparency, you have the option
of combining several G-code blocks to form program blocks.
Program blocks can be created in two stages. This means that you can form additional blocks
within a block (nesting).
You then have the option of opening and closing these blocks depending on your requirement.
