Hi This is shankar

1. for load all sub file the page up and page down is handle by the system it self so
when you enter page down at last you have to identify the system defined symbol as well as page up.
2.for Expandable subfile page up is handled by the system if you enter page up at last you have to identify the system defined symbol that is called expandable sub file.
3.for single page subfile page up and page down is handled by the user so when you page or page down at top /bottam you have to identify the this ÿou have already reached the top/you have already reached the bottam this is called  single page subfile

    No. It's not even possible to tell if a subfile is used at all without looking into job details. -- Tom

    You generally can't tell when you're looking at the screen

    You can get some clues from the screen control file code. 

     

    .. if sflpage = sflsize it is a page-at-a-time (single page) subfile.

    if the dds has a pageUp (rollDown) then it's likely to be a page-at-a-time

    If the dds doesn't have a pageUp (rollDown) but does have a pageDown (rollUp) then it's likely to be a "Load Forward" subfile

    If the dds doesn't have either a pageup or pagedown it's likely to be a load all subfile.

    And if it's an array defined over a record format, there is no subfile. And if it's UIM source, then it's a UIM list area rather than a subfile. And if there's no display source at all, it's probably DSM formatting. And if the programming is COBOL with DDS but no subfile records, it's possibly using BEFORE/AFTER ROLLING clauses. There are many ways of making a screen look the same and behave the same as a subfile without using a subfile. -- Tom
