Using option "18=Formals" with an Entry on the panel Work with Entries displays the list of all Formal parameters of the Entry on the panel Work with Formal parameters. If the Entry was generated this list was created in the generation process. If the Entry is created manually this list is initially empty. The Formal parameters of an Entry are the information that is needed to retrieve the intended records when the Entry is used.
There are two versions of the panel "Work with Formal parameters"; the 'normal' one that will be displayed when an Entry is already created and a special one that is displayed as a part of the Entry generation process.
On the special "Work with Formal parameters" only the name of a Formal parameter can be changed and Formal parameters can be dropped or retrieved when they were previously dropped. Only options "4=Drop key field", "6=Retrieve key fields" and "7=Convert to valid ITP name" are available. On the normal "Work with Formal parameters" panel the Formal parameters of the Entry can be manipulated.
