Re: How to view data in alphabetical order in a subfile

You can also code the SFLRCDNBR keyword in your subfile then position to 
the record.  I like this because the user can still page up and down 
through the whole subfile.  Sometimes users don't understand when the 
subfile starts somewhere in the middle and they press 'page-up' and 
receive a message saying they're at the top of the subfile.  Here's a very 
abbreviated sample of the coding:

In the display-file DDS, code  the following keyword on the record (before 
any fields are defined):

     A            SFLRCDNBR      4S 0H      SFLRCDNBR(CURSOR)

In your program, read sequentially through the subfile and compare the 
position-to value:

       .       .       .
       .       .       .
       .       .       .

           perform Scan-subfile
               varying SFLRRN from 1 by 1
               until SFLRRN > Save-max-rrn

       .       .       .
       .       .       .
       .       .       .

       Scan-subfile.
           read subfile Display-file
                   into        List-detail
                   format      'DETAIL'
                   invalid key
                       continue
           end-read
           if Lastname of List-detail >= Save-lastname
           or SFLRRN = Save-max-rrn
               move SFLRRN to SFLRCDNBR
               move Save-max-rrn to SFLRRN
           end-if
