Note: Before CitectSCADA version 5.0, page records
could be edited in the Project Editor. One of the fields available
for configuration was "Page Number". The value entered for a page
could then be used in runtime with the Page Cicode functions such
be used to display the page that has "1" (without the quotes) set
in the PageNumber field.
PageInfo(1) returns the Page Number
of the current page.
From version 5.0 on, this feature is only backwards-supported. The "Alias" field in the project Pages.DBF file still contains the Page Numbers from upgraded projects; however, the Pages database records are no longer available for direct editing in CitectSCADA.
