Item Action flag

The T-TBLX-ITEM-ACTION flag is determined when the editor is invoked and should be treated as read-only. Typically, it is identical to the I/O indicator, T-TBLX-EXIT-IO-IND. If the terminal user keys in U for Update in selecting a row, then decides to create a new row and keys in NEW on the command line, the user’s intent changes and these flags will be different. In this case the exit program will be provided with ITEM-ACTION U for Update and IO-IND N for New.
