Re: Subfile "move to top" function

Booth,

I'm looking to do the equivalent of a position-to within a loaded subfile. This is a load-all subfile.

Example:
Subfile page size = 10

Number of records loaded = 32

Page 2 is displayed and the cursor is on the 4th record of the page, which is the 14th record loaded.
If the user presses a function key I would like the 4th record on the page (aka the 14the subfile record) to be the beginning record on that page. Page up would then display the previous 10 records,
starting at RRN 4. Page up again would reposition the first line starting at RRN1.

I would also like full control using SFLRCDNBR to able to position the cursor and page for other functions.

Is this easy to accomplish via SFL keywords? Or do I need to reload the subfile and add additional paging logic?

Instead of conditioning it, just set the TOPREC field name to 1 unless
you have a reason to set it to a higher value. For instance you can do
(TOPREC = number-of-records - page-size) to show a full last panel on
start up.
