• PresentationName is the alternative name to present the parameter. This is a convenient way in case you would like to use special characters (spaces, mathematical characters, etc.) in a parameter name to be presented to the user, that are not allowed in the name used for the syntax. Or to get rid of special characters required in the syntax you do not want to show to the user (#, $, etc.).
• See also Documentation of knowledge. 

Remarks

Presentation of the parameters in the Workbase also depends on the presentation option selected in the combobox above the list in the Workbase.
