PROMPT rendering and behavior

This topic describes differences between I4GL and FGL PROMPT instruction in TUI mode.

ESC key validates the PROMPT

With IBM® Informix® 4GL, when you press the ESC key during a PROMPT, the interactive instruction continues. User has to hit the ENTER key to validate the input.

With Genero BDL, in TUI mode, an ESC keypress will validate the PROMPT dialog, like other single-dialogs such as INPUT.

The behavior of Genero BDL is more consistent than I4GL in this context.
