Skipping blocks

NC blocks, which are not to be executed every time the program runs, can be skipped and not
processed. This function is used when testing and/or running-in new programs, for example.
Skip blocks
Blocks to be skipped are indicated in the part program by the character "/" before the block
number. Several consecutive blocks can also be skipped. The instructions in the skipped
blocks are not executed and the program resumes with the next block that is not skipped.
