GST Initial setting

The loading of the tool list is illustrated in the program example. Loading is started via an H
word which sets flag F 100.2. This flag is reset by another H word (F 100.1) as soon as the
leader is finished.
Using the R parameter R 150, the leader of the machining program is skipped.
