PM:
When an action on the screen occurs your program is going to do a read.
You can only read one record format and I don't think there is any way
to
know which record format to read.
It is not as difficult as it might seem. I don't use EXFMT for
the very reason that you have to know which format you want to read. I
use a WRITE of the subfile control record format as the last part of
building the screen, of course. From there I can do a READ of the display
file rather than reading a particular record format. This way the 5250
controller will return whichever record format is ready to be received and
the file feedback area will contain the name of the record format returned
in this manner. Another read will return any other record format that
*might* be read to be received -- but don't count on it. Rather, you can
use READC of a particular subfile to determine if that subfile has been
modified. That said, I admit that I've never used side-by-side subfiles
so I am not sure of the actual answer for the OP.
Sincerely,
