FORMULA LANGUAGE

Examples: @Return
1. This formula displays a dialog box offering the user a Yes/No choice. If the user selects Yes, the next document in the view is opened; if the user selects No, the formula stops and nothing more happens.

@If(@Prompt([YesNo];"Continue?";"Do you want to continue reading your mail?");@Command([NavNext]);@Return(""))

2. This formula tests whether an environment variable called OrderNumber has been stored in the user's NOTES.INI or Notes Preferences file. If there is no such variable stored, @SetEnvironment is used to initialize it to zero. If a value has already been stored, @Return is used to return it and stop the formula from executing.

@If(@Environment(OrderNumber)="";@SetEnvironment("OrderNumber"; "0");@Return(@Environment("OrderNumber")))

3. The following code, when added to a field that displays the result of a database lookup, returns a customized error message if an error is encountered during that lookup. The temporary variable, "lookup," retrieves the job title (located in column 3 of the "People" view) of the person listed in the first sorted column of the "People" view. If an error is encountered during the lookup, the field displays the specified error message in a dialog box and "1" displays in the field, indicating that there was an error encountered.

lookup := @DbLookup("" : "" ; "serverName" : "fileDirectory\\databaseName.nsf"; "People" ; "Jackie Brown"; 3);

@If(@IsError(lookup); @Return(@Prompt([OK];"Error";"Error locating the requested job title. Aborting lookup")); lookup)
