FGLGUI is 1 by default
In Four Js Business Development Suite (BDS), when the FGLGUI environment variable is not set, the application starts in TUI mode (FGLGUI=0).
With Genero BDL, the default is GUI mode (FGLGUI=1). Therefore, when migrating from Informix® 4GL, it is recommended that you set FGLGUI=0 to run the application in text mode as a first step.
