Subfile display problem

It would help if you posted some code. Dave

It appears to me that your page up routine is something like this:

C FirstRcd SetLL File

C1DoSflPag RRN

C ReadP File

C If%eof

C Leave

C Else

C Write Sfl

C Endif

C EndDo

In otherwords, you are reading backwards but filling the subfile forwards. You have two options; you can read backwards the number of records in a page of the subfile and then fill the subfile reading forwards, or you can fill the subfile backwards as you are reading backwards. Examples follow:

C FirstRcd SetLL File

C 0 DoSflPag

C ReadP File

C EndDo

C If%eof(File)

C*LoValSetll File

C Endif

C 1DoSflPag RRN

C ReadFile

C If%eof

C Leave

C Else

C Write Sfl

C Endif

C Enddo

C FirstRcd SetLL File

C 1DoSflPag x

C ReadP File

C If%eof

CLeave

CElse

C Eval RRN = SflPag -x + 1

C Write Sfl

C Endif

C EndDo

You dont need to do a readp for doing page up. Subfile records once filled are still stored in the subfile, until you clear the subfile records. Simple pageup will bring you back the records that are already filled. Remove the codes for rebuilding the subfile using readp. Add records only during page-down. Hope this helps. Elan

Hi, My problem is the following I have a subfile which is loade normally (one page a time), when i perform a page up, the next page is displayed, but when i perform a page down, the first page is displayed but in reverse order .

Thanks a lot for your help . I finally find why my subfile was reversed, it was because i used indicators for conditionning some fields . Regards Mamadou TOURE
