Automatic Record Advance CHECK(ER)

["Shaheen Ahmed" <Syed.Ahmed@xxxxxxxx>]

Is there any way to differentiate between Automatic Record Advance CHECK(ER) 
and Enter key in RPG.
I have a subfile to enter 60 characters memo (3 lines on each page). When user 
press ENTER key RPG program writes records into a physical file. If user wants 
to enter more then three memo lines then I want to display the next subfile 
page without creating first three records into the physical file. I used 
CHECK(ER) on subfile field so that when the cursor is on last row and last 
column it should take user to the next subfile page automatically. My question 
is.......Is there any way to know user press ENTER key or CHECK(ER).
