However, your comment was prompted by a reference to RPG Open I/O and that
has nothing to do with the 5250 data stream itself.
Well, it somewhat does because it gives you access to things that before, as
I understand it, were only available to certain vendors. For example, I
could have a display file with input fields in it. I could do an EXFMT and
dynamically intercept and process the layout of that display file and put it
to the web page. Then on the way back in, after a user event, I could map
those values to the display file input fields, and those fields are already
readily available to the RPG program - no need to call CGI API's to load
data. That is a nice feature to save on lines of code and thus save on
program complexity.
I am not an expert on the front of 5250 or work station controllers but only
make comments as to how I see them work. Please correct my understanding
where I am wrong.
