4=Delete
Delete the registration of Subentry with the Entry (including the Actual parameters).
5=Display
Display the primary attributes of the Subentry.
This exactly the same function as when option "5=Display" is used on the "Work with Entries" panels with the Entry that is registered as Subentry
18=Actual parameters
The list of all Actual parameter definitions is prompted on the "Work with Actual parameters".
21=Check sub entry
Checks if the definition of Formal parameters of the Subentry are consistent with the Actual parameters specified.
An Entry can only be listed once as a Subentry of another Entry. If more than one relation between two Entries exist Aliases should be used to define the role of an Entry in the relation. These Aliases can then be registered as the Subentries. Refer to Work with Aliases of entry for more information.
