Hi Dave

(any follow-ups would probably be more relevant to RPG400-L)

It sounds doable. We have a similar application that users seem to find
okay - at least I've not had any complaints in the eight years they've
been using it ;) Instead of using EXFMT, just use WRITE & READ like this

     C                     WRITEFOOTER1
     C                     WRITEMSFLC                      MSG SUBFILE
     C                     WRITESFLCTL1
     C                     WRITESFLCTL2
     C                     READ SFLCTL1                  75
     C                     READ SFLCTL2                  75

Using the RTNCSRLOC DDS keyword your app can determine which record
format the cursor is in when the user scrolls, and do the magic with the
right subfile. If you want to see an example in action, have a look at
http://www.dbg400.net/extras.html and look for EMS. Look at members
EMSRG010 (RPG) and EMSDF010 (DSPF) in ALLSRCMBRS in the download package
http://www.dbg400.net/download/extras/ems/emscode.zip
