Initial setting
At the initial setting, the data blocks of the tool list are set up and the status words of

Program example:
The loading of the tool list is illustrated in the program example. This function is started via an
H word which sets the flag F 100.2. This flag is reset by another H word (F 100.1) at the end
of the leader.
The R parameter R 150 determines whether the leader of the machining program is skipped.
