eScript query BC by page

Hello All,

I have been trying to identify any documented method that will allow me to query for records on a BC page wise like first 10 or 20 records and then next 10 or 20, using eScript.

I see there is a direct way of doing so in list applets i.e. a list applet displays first 10 or 20 number of rows in UI and on click of next record set button it will fetch next set/page. Also the BC instance on UI has same number of records in context.

I want to mimic above using eScript, but could not find any documented method. All I can do is use an iterator and a count to skip or set offset to read fields values using FirstRecord and NextRecord methods.
