User messages and alerts
MsgInfo(cTexto,cTitulo); MsgStop(cTexto,cTitulo); MsgYesNo(cTexto,cTitulo)Chooses information, warning or confirmation for the workflow.
Overview
MsgInfo conveys information; MsgStop signals a warning; MsgYesNo asks for a decision. An error icon does not undo writes and confirmation does not execute an action itself. The consulted community samples show these interaction differences. This adaptation retains one confirmation without a business operation. Jobs should use logs and processing state instead of modal windows. (Sources: refs. 1–4.)
