An MFS screen is "connected" to an IMS DC program. The fields on the MFS screen match the fields defined in the IMS DC program. The edits for each field are programmed in that IMS DC program. The IMS DC program determines if the field on the screen was entered correctly. If so, it then updates the corresponding field in the IMS database.
