Compatibility for cycle support

The cycle support is generally upwards compatible. This means that cycle calls in NC programs
can always be recompiled with a higher software version, changed and then run again.
When transferring NC programs to a machine with a lower software version, it cannot be
guaranteed, however, that the program will be able to be changed by recompiling cycle calls.

Press the <SHIFT + INSERT> key combination.
This starts the edit mode for this cycle call and you can edit it like a normal
NC block. This means that it is possible to generate an empty block
before the cycle is called. For instance, to insert something before a cycle
that is located at the beginning of the program.
Note: In edit mode, the cycle call can be changed in such a way that it can
no longer be recompiled in the parameter screen.
You exit the edit mode by pressing the <SHIFT + INSERT> key combi‐
