Variable Declaration Window
The variable declaration window is displayed to the left of the work area and is
used to declare variables. In the left half of the variable declaration window, you will
see the declaration sections and on the right-hand side the detailed information of
the component selected on the left.
In the variable declaration window, you can modify existing parameter sets, system
parameters can be deleted but cannot be edited. It is also possible to extend your
own parameters.
If you want to use a parameter in the sequencer, you can drag it from the variable
declaration window to the sequencer using the mouse and position it at the
required location.
Changes you have made to the parameters in the variable declaration window are
automatically updated in the sequencer so that no inconsistencies can result.
With the F1 key, detailed help is available on declaring variables in the variable
declaration window.
