Skipping blocks

NC blocks which are not to be executed in every program pass (e.g. execute a trial program
run), can be skipped.
Programming
Blocks which are to be skipped are marked with an oblique "/" in front of the block number.
Several consecutive blocks can also be skipped. The statements in the skipped blocks are not
executed; the program continues with the next block which is not skipped.
