5.5.2 Track types
Main track
The main track contains the main sequence of the method and exists in each
method. It starts with a start command START and finishes with a end command
END . The method variables are defined in the start command. The end command
indicates the end of the method run. The main track can neither be deleted nor
moved.
Normal track
A normal track is a track that can be created manually with Insert, New track,
Normal track or with the icon . It starts with a start command TRACK and finishes
with a end command END .
Normal tracks can be called with the command CALL . Branching and parallel
processes can be realized. The following two cases can be differentiated when
calling normal tracks:
• Sequential running normal tracks
If the option Return immediately is switched off in the command TRACK , all
commands of this track are executed one after the other when this normal
track is called. As soon as the track has been finished it sends an acknowl-
edgement to the calling command
CALL and the run is continued there.
• Parallel running normal tracks
If the option Return immediately is switched on in the command TRACK , the
command is marked with an arrow (see below). The execution of the com-
mands in the normal track is started when this track is called but it sends
an acknowledgement immediately to the track containing the correspond-
ing command CALL . The calling track is being continued i.e. both tracks are
running simultaneously.
