I read data from a list using the notation "&[_listline(nn)]" where nn is the line number 1,2,3,... This works fine on the first page (51 lines) but "&[_listline(52)]" and the following ones are always empty. Why?
The line numbers start with 1 for each new page. 
In order to get all the lines of a list you have to scroll page by page, starting with line 1 for each page.
