In here the total deck area will be calculated and the result will be send back to Quaestor in to Quaestor in the parameter “Total_deck_area”. First store the Excel file Example.xls in the current applications directory (either of the knowledge base, located in Kbs\_<KnowledgeBaseName>\Applic, or the general Applic directory in My Knowledge).

Create the following relations in Entity “Data to Excel”:

• Loa = ENTITY#(xx).Loa ; In which “xx” is the QEntityID of Entity ”Main Dimensions”
• Lpp = ENTITY#(xx).Lpp ; In which “xx” is the QEntityID of Entity ”Main Dimensions”
• Boa = ENTITY#(xx).Boa ; In which “xx” is the QEntityID of Entity ”Main Dimensions”
• Dm = ENTITY#(xx).Dm ; In which “xx” is the QEntityID of Entity ”Main Dimensions”
• Deck_data# = ENTITY#(xx). Deck_data# ; In which “xx” is the QEntityID of Entity ”Decks”
• File_name_Excel$ = "Deck_data_" + STR$(TIME(0)) + ".xls"
• Total_deck_area = Data_to_excel$.Total_deck_area
• To show computed values during a dialogue write “@SHOW” behind “QEntityData”.

Parameter “Data_to_Excel$” contains the EXCEL#() function. Create the relation as shown in Figure 85. EXCEL#() function returns the result of an EXCEL spreadsheet calculation in TeLiTab format. See the wiki for a detailed description of EXCEL#() function.
