OK_CODE to '=/BDA' when you want to give a user control at a specific screen during a call transaction

Set OK_CODE to '=/BDA' when you want to give a user control at a specific screen during a call transaction.

So instead of run mode A where you see all the screens or run mode E where you only see the errors, you can use run mode N and then stop the program on a specific screen and give the control to the user. When the user finishes the transaction the control goes back to the program, I think.
