Skip blocks

You can skip program blocks that are not to be executed every time the program runs.
The skip blocks are identified by placing a "/" (forward slash) or "/x" (x = number of skip level)
character in front of the block number. You have the option of hiding several block sequences.
The statements in the skipped blocks are not executed. The program continues with the next
block, which is not skipped.

Mode of operation
In the program, the measurement results screen display is activated while machining.
Program processing stops at the points you defined as relevant to stop before the program
started. These may be, for example, especially critical points, at which you can check the cor‐
rectness of the sequence or exclude collisions.
The following NC function transitions can be activated as default setting in window "Program
control" as stop relevant:
• Transition G1-G0
• Transition G0-G0
You can also define NC functions (auxiliary functions, cycle calls, T-preselection) as NC function
transitions.
