Procedure Parameters
The Procedure Parameters are all such parameters that are separate from
the previously described categories. They are shown on the right side of
the ValiFrame user interface. They appear when the selected entry of the
procedure tree on the left is an individual procedure. These parameters
only change the behavior of the selected procedure. Procedures often
have parameters with the same name, but the configured settings always
apply on the selected procedure, and the meaning may be slightly
different.
