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 acknowledgement to the calling command
CALL and the run is con-
tinued 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 commands in the normal track is started when this track is called
but it sends an acknowledgement immediately to the track containing
the corresponding command
CALL . The calling track is being contin-
ued i.e. both tracks are running simultaneously.
